Therefore the positive ions must be Fe3+, Cu2+, Ga3+, Cr3+, Ti3+ and Co3+. Translating oxyacids from formula to name involves dropping the word hydrogen completely, replacing the anion’s suffix, and adding acid. Ionic/Covalent Compound Naming Solutions 1) Na 2 CO 3 sodium carbonate 2) P 2 O 5 diphosphorus pentoxide 3) NH 3 ammonia 4) FeSO 4 iron (II) sulfate 5) SiO 2 silicon dioxide 6) GaCl 3 gallium chloride 7) CoBr 2 cobalt (II) bromide 8) B 2 H 4 diboron tetrahydride 9) CO carbon monoxide 10) P 4 All acids have some similar properties. The chemistry of these compounds is explored in more detail in later chapters of this text, but for now, it will suffice to note that many acids release hydrogen ions, H+, when dissolved in water. 3 - Chemical Quantities and Stoichiometry, 4 - Types of Chemical Reactions and Solution Stoichiometry, 7 - Quantum Mechanical View of the Atom, and Periodicity, 9 - Covalent Bonding and Molecular Orbitals, 10 - Liquids, Solids, and Intermolecular Forces, 15 - Applications of Acid-Base Equilibria, 16 - Spontaneity, Entropy, and Free Energy, 18 - Transition Metals and Coordination Chemistry, 20 - An Introduction to Organic Chemistry, 1 - Structural, Bonding, Molecular Properties, 2 - The Nature of Organic Compounds: Alkanes and Cycloalkanes, 3 - Stereochemistry of Alkanes and Cycloalkanes: 3-D Structures of Molecules, 4 - The Study of Organic Reactions: An Overview, 10 - Substitution (SN2, SN1) and Elimination (E2, E1) Reactions, 11 - Mass Spectrometry and IR Spectroscopy, 13 - Conjugated Systems and UV Spectroscopy, 15 - Electrophilic Aromatic Substitution (E.A.S. a)  dinitrogen pentoxide         b)  tetraboron tricarbide         c)  phosphorus pentachloride. When two nonmetallic elements form a molecular compound, several combination ratios are often possible. Remember, they may be either ionic or covalent compounds, so make sure you use the right naming method! Here is some tips, and tricks for naming ionic compounds. 1. For example, sodium chloride melts at 801 °C and boils at 1413 °C. Write the formulas of the following ionic compounds: a) chromium(III) phosphide        b) mercury(II) sulfide         c) manganese(II) phosphate, d) copper(I) oxide         e) chromium(VI) fluoride, a) CrP         b) HgS        c) Mn3(PO4)2         d) Cu2O         e) CrF6. We have already mentioned that citrus fruits contain acid; among other compounds, they contain citric acid, H3C6H5O7(aq). Okay I have a chemistry question. Write the proper formula and give the proper name for each ionic compound formed between the two listed ions. The name of an ionic compound also gives you information about the oxidation numbers of the elements. The anion is named by taking the elemental name, removing the ending, and adding “-ide.” The name of a binary molecular compound ends in “ide”, just like the name of a binary ionic compound. Acids are very prevalent in the world around us. Instead, retain the suffix of the polyatomic ion. Test. However, we will briefly discuss the important compounds known as oxyacids, compounds that contain hydrogen, oxygen, and at least one other element, and are bonded in such a way as to impart acidic properties to the compound (you will learn the details of this in a later chapter). Molecular compounds are made when two or more elements share electrons in a covalent bond to connect the elements. Flashcards. Thus H2S(aq) = hydrosulfuric acid. 30 seconds . a)  XeF2         b)  O2F2         c)  SF6. The simplest form of a covalent compound would be a non-metal / non-metal pair made of two single elements (NO for example). The other fluoride of tin is SnF4, is now named tin(IV) fluoride but is still often referred to as stannic fluoride. September 27, 2020. Give the formula and name for each ionic compound formed between the two listed ions. Binary acids are composed of hydrogen and one other element, while oxyacids contain hydrogen, oxygen, and another element. c) Neither charge is an exact multiple of the other, so we have to go to the least common multiple of 6. Every day you encounter and use a large number of ionic compounds. Acids make certain plant pigments change colors; indeed, the ripening of some fruits and vegetables is caused by the formation or destruction of excess acid in the plant. Typical oxyacids consist of hydrogen combined with a polyatomic, oxygen-containing ion. Other examples are provided in Table 4. ), 18 - Aldehydes and Ketones: Nucleophilic Addition Reactions, 20 - Carboxylic Acid Derivatives and Nucleophilic Acyl Substitution Reactions, 21 - Carbonyl Alpha-Substitution Reactions, choosing a selection results in a full page refresh. Typically, non-metals tend to share electrons, make covalent bonds, and thus, form molecular compounds. If the compound is a binary acid (comprised of hydrogen and one other nonmetallic element): For example, when the gas HCl (hydrogen chloride) is dissolved in water, the solution is called hydrochloric acid. b) Because the ions have the same magnitude of charge, we need only one of each to balance the charges. Some metal cations can have multiple charges. a)  Cu2+ and F−         b)  Ca2+ and O2−         c)  K+ and P3−. View Lab Report - Lab05_Naming Ionic and Molecular Compounds.docx from CHEMISTRY 301 at University of Karachi. The common table salt we use on our foods is an ionic sodium compound. Because Br has a charge of –1, we know that Sn must have a charge of +4. When writing the name of ionic compounds the name of the metal is always written first. Then use these Qcards to quiz yourself. The charges of cations and anions dictate their ratios in ionic compounds, so specifying the names of the ions provides sufficient information to determine chemical formulas. Anions are named using the stem of the element name with the suffix -ide added. Ionic bonds occur between two species which are electrostatically attracted towards each other , whereas covalent bonds from through the sharing of electrons between their outer shells . The first thing we need to do is figure out what kind of compound we are working with, as ionic and covalent compounds have very different naming systems. Despite cleanup efforts, Cr(VI) groundwater contamination remains a problem in Hinckley and other locations across the globe. Formulas of Covalent Compounds • Phosphoric acid is an ingredient in some soft drinks. When two vowels are adjacent, the a in the Greek prefix is usually dropped. 13. 10. a)  phosphorus trifluoride         b)  tellurium dichloride         c)  dinitrogen trioxide, 11. a)  xenon difluoride         b)  dioxygen difluoride         c)  sulfur hexafluoride, 12. a)  dinitrogen monoxide         b)  dinitrogen tetroxide         c)  dinitrogen pentoxide, 13. a)  N2O5         b)  B4C3         c)  PCl5, 14. a)  O2Cl2         b)  N2S3         c)  XeF4, 15. a)  IF3         b)  XeO3         c)  S2F10, 17. a)  hydrofluoric acid         b)  nitric acid         c)  oxalic acid, 18. a) cesium chloride         b) barium oxide         c) potassium sulfide, d) beryllium chloride         e) hydrogen bromide         f) aluminum fluoride, 19. a) RbBr         b) MgSe         c) Na2O         d) CaCl2         e) HF         f) GaP         g) AlBr3         h) (NH4)2SO4, 20. a) ClO2         b) N2O4         c) K3P         d) Ag2S         e) AlN         f) SiO2, 21. a) chromium(III) oxide         b) iron(II) chloride         c) chromium(VI) oxide, d) titanium(IV) chloride         e) cobalt(II) oxide         f) molybdenum(IV) sulfide, 22. a) K3PO4         b) CuSO4         c) CaCl2         d) TiO2         e) NH4NO3         f) NaHSO4, 23. a) manganese(IV) oxide         b) mercury(I) chloride         c) iron(III) nitrate, d) titanium(IV) chloride         e) copper(II) bromide, binary acid: compound that contains hydrogen and one other element, bonded in a way that imparts acidic properties to the compound (ability to release H+ ions when dissolved in water). Compounds containing polyatomic ions are named similarly to those containing only monatomic ions, except there is no need to change to an –ide ending, since the suffix is already present in the name of the anion. CHEM 1114 - Introduction to Chemistry by Shirley Wacowich-Sgarbi is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License, except where otherwise noted. the phosphide anion and the strontium cation, a)  SnBr4         b) CoCl3          c)  Fe2O3. Naming Ionic and Molecular Compounds Game. If only it were that easy. Oxyacids are named by changing the ending of the anion to –ic, and adding “acid;” H2CO3 is carbonic acid. From the answers we derive, we place the compound in an appropriate category and then name it accordingly. Na is a Group 1 metal, and thus it forms the cation Na+, called “sodium” ion. Because the metal ions in questions a) to f) have a variable charge, we must figure out the charge of the metal ion by ensuring that the total number of positive charges in each compound must equal the total number of negative charges. You can choose binary, polyatomic, and variable charge ionic compounds, as well as molecular compounds. The oxyacid suffix replacements are -ate becomes -ic and -ite becomes -ous. Some compounds containing hydrogen are members of an important class of substances known as acids, and these compounds have interesting chemical properties. Ionic compounds are compounds composed of ions, chargedparticles that form when an atom (or group of atoms, in the case of polyatomicions) gains or loses electrons. Translating binary acids from formula to name will end up in the format hydro[root of anion]ic acid. 7. The simplest name, “iron chloride,” will, in this case, be ambiguous, as it does not distinguish between these two compounds. Covalent compounds, often called "molecular compounds," consist of two non-metals; a non-metal / non-metal pair. Here's how... Start by examining the chart below and visualizing how we convert "compound formulas" into "compound names.". Name each acid without consulting the tables. Instead, retain the suffix of the polyatomic ion. Three examples are below. It is not calcium(II) chloride because calcium forms only one cation when it forms an ion, and it has a characteristic charge of 2+. Covalent compounds, often called "molecular compounds," consist of two non-metals; a non-metal / non-metal pair. Cross over the charges (oxidation numbers) 3. Below is a chemistry quiz on ionic compounds, names, and formulas, give it a shot and see if you understood all we covered in this topic on Ions. "What do you mean?" Knowing both convention remains important. Chromium compounds are widely used in industry, such as for chrome plating, in dye-making, as preservatives, and to prevent corrosion in cooling tower water, as occurred near Hinckley. Log in Sign up. Give the non-metal its ion name (with the ide ending) Ex: NaCl sodium chloride BaF 2 barium fluoride Writing Ionic Compound Formulas: Crossover method 1. The key difference between ionic and molecular compounds is that the ionic compounds have electrostatic attraction forces between cations and anions whereas the molecular compounds have only covalent chemical bonds between the atoms.. Chemical elements can join with each other to form chemical compounds. Ionic compounds are made of ionic bonds, and molecular compounds are made of covalent bonds. Follow the same naming conventions as with monatomic ions, except for the step wherein the suffix is changed to. a)  Pb4+ and SO42−         b)  Na+ and I3−         c)  Li+ and Cr2O72−. Search. Binary acids are named using the prefix hydro-, changing the –ide suffix to –ic, and adding “acid;” HCl is hydrochloric acid. Browse. Tags: Question 7 . November 13, 2020, How to Name Ionic and Covalent Compounds Similarly, N2O is known as nitrous oxide even though our rules would specify the name dinitrogen monoxide. The name of the more metallic element (the one farther to the left and/or bottom of the periodic table) is first, followed by the name of the more nonmetallic element (the one farther to the right and/or top) with its ending changed to the suffix –ide. Chemists use nomenclature rules to clearly name compounds. Table 10. Examples are shown in Table 2. These elements will be found on the far right side of the periodic table - to the right of the metalloid staircase.The simplest form of a covalent compound would be a non-metal / non-metal pair made of two single elements (NO for example). .Which of these formulas represent molecules? 2. The cation has the same name as its element. Only use numerical prefixes for the first element when the molecule contains more than one of that atom. For example, K2O is called potassium oxide. Some of them you may recognize after reading this chapter. These two compounds are then unambiguously named iron(II) chloride and iron(III) chloride, respectively. If only it were that easy. If the compound is molecular, does it contain hydrogen? October 11, 2020, 5 Great Ways to Get Chemistry Help Each of the following compounds contains a metal that can exhibit more than one ionic charge. Many compounds containing three or more elements (such as organic compounds or coordination compounds) are subject to specialized nomenclature rules that you will learn later. If the first element you "see" in the compound is found on the left side of the periodic table (i.e. An ionic compound always has two parts. This will be marked by the subscript "aq," as shown in the examples below. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. How to Name Compounds • This is the cobalt(II) cation. In fact, the human body is approximately 0.15% sodium, with the average person having one-twentieth to one-tenth of a kilogram in their body at any given time, mostly in fluids outside cells and in other bodily fluids. SURVEY . There are a few common names that you will encounter as you continue your study of chemistry. However, because covalent bonding allows for significant variation in the combination ratios of the atoms in a molecule, the names for molecular compounds must explicitly identify these ratios. An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal, and the resulting ions have achieved an octet. Naming Ionic and Molecular Compounds Hands-On … The name of the cation comes first and is used as is; the name of the anion comes second and has the last part changed to -ide. You can often recognize ionic compounds because of their properties. The root is “cyan”, thus HCN(aq) = hydrocyanic acid. For example, consider binary ionic compounds of iron and chlorine. 3. Give the formula and name for each ionic compound formed between the two listed ions. a) NH4+ and PO43−          b) Co3+ and NO2−, a) (NH4)3PO4, ammonium phosphate          b) Co(NO2)3, cobalt(III) nitrite. you ask… Well it's also possible to have ionic compounds that contain polyatomic ions. (When an ion consists of more than one element, we … d)  HCN(aq) contains the polyatomic ion cyanide. you ask… Well it's also possible to have ionic compounds that contain polyatomic ions. Naming Ionic Compounds Video; Multivalent Ionic bonding. 11. a)  iodine trifluoride         b)  xenon trioxide         c)  disulfur decafluoride, a)  perchloric acid         b)  hydroiodic acid, a)  HF(aq)         b)  HNO3(aq)         c)  H2C2O4(aq), a) CsCl         b) BaO         c) K2S         d) BeCl2         e) HBr         f) AlF3. Chemical Reactions and Equations, 6.1 Writing and Balancing Chemical Equations, Chapter 7. Look at the label or ingredients list on the various products that you use during the next few days, and see if you run into any of those in this table, or find other ionic compounds that you could now name or write as a formula. However, there has been a push to reduce the amount of sodium most people ingest every day: avoid processed and manufactured foods, read labels on packaged foods (which include an indication of the sodium content), don’t oversalt foods, and use other herbs and spices besides salt in cooking. Find the ratio of positive ions to negative ions that results in a net charge of zero. b) Because this species has no charge, it is an atom in its elemental form. The name and the formula usually begin with the element that is more to the left on the periodic table. Give the proper formula for each name. Naming Ionic Compounds, Naming molecular compounds. For ionic compounds, start by listing the component ions. If so, does it also contain oxygen? To name covalent compounds that contain up to three elements. For example, acids have a sour taste; in fact, the sour taste of some of our foods, such as citrus fruits and vinegar, is caused by the presence of acids in food. 7. As with ionic compounds, the system for naming covalent compounds enables chemists to write the molecular formula from the name and vice versa. Ionic compounds are formed of a metal (cation) and a non-metal (anion). They have more than one ions. Write the formulas for each compound: a) potassium phosphate         b) copper(II) sulfate         c) calcium chloride, d) titanium dioxide         e) ammonium nitrate, f) sodium bisulfate (the common name for sodium hydrogen sulfate). Give the formula and name for each ionic compound formed between the two listed ions. Stoichiometry of Chemical Reactions, 7.4 Other Units for Solution Concentrations, 8.2 Quantization of the Energy of Electrons, Chapter 9. Log in Sign up. Naming compounds that contain metals with multiple charges is done much the same way as naming other ionic compounds with one crucial difference: the charge of the metal is included in the compound name using roman numerals. To indicate that something is dissolved in water, we will use the phase label (aq) next to a chemical formula (where aq stands for “aqueous,” a word that describes something dissolved in water). . A cationis a positively charged ion 2. Make yourself a stack of small sized Qcards. Learn. Translating binary acids from formula to name will end up in the format, Translating oxyacids from formula to name involves dropping the word hydrogen completely, replacing the anion’s suffix, and adding acid. Give the metal its full name 2. We will limit our attention here to inorganic compounds, compounds that are composed principally of elements other than carbon, and will follow the nomenclature guidelines proposed by IUPAC. In this case, however, the root takes a slightly different form of “sulfur” (the same as the element name). There are some exceptions to the general naming method (e.g., H2SO4 is called sulfuric acid, not sulfic acid, and H2SO3 is sulfurous, not sulfous, acid). What are the IUPAC names of the following compounds? For example, although NO is often called nitric oxide, its proper name is nitrogen monoxide. Because these compounds consist solely of nonmetals, they are molecular compounds, therefore according to the rules, we use prefixes to designate the number of atoms of each element: a) sulfur hexafluoride                    b) dinitrogen trioxide              c) dichloride heptoxide, d) tetraphosphorus hexoxide         e) phosphorus trifluoride         f) carbon monoxide (not carbon monooxide). Naming Ionic Compounds Ionic compounds are named using the name of the cation and anion that make up the compound. You can find metals on the left and central sections of the periodic table (e.g., Barium, Radium, and Lead), while you can find non-metals on the right side of the table. Exposure to small amounts of Cr(VI) can lead to damage of the respiratory, gastrointestinal, and immune systems, as well as the kidneys, liver, blood, and skin. Give the proper formula for each name. Rules for Naming Molecular Compounds: Remove the ending of the second element, and add “ide” just like in ionic compounds. 23. Spell. . Give the proper formula for each diatomic element. 0 = 1(x) + 4(-1)                       x = +4         Therefore SnBr4=  tin(IV) bromide, 0 = 1(x) + 3(-1)                       x = +3         Therefore CoCl3= cobalt(III) chloride, 0 = 2(x) + 3(-2)                       x = +3         Therefore Fe2O3= iron(III) oxide, a)  HgO            b)  PbCl4          c) PbS           d) Sc2O3         e) AgCl, a) mercury(II) oxide         b) lead(IV) chloride         c) lead(II) sulphide, d) scandium oxide         e) silver chloride, a) Fe2S3         b) CuSe         c) GaN         d) CrCl3         e) Ti2(SO4)3         f) Co2O3         g) CaCl2         h) AlF3. We have discovered how to change chemical formulae into names of chemicals. Formulas of Molecular Compounds • If the compound is ionic, does the metal form ions of only one type (fixed charge) or more than one type (variable charge)? To deal with this situation, we use a naming method that is somewhat similar to that used for ionic compounds, but with added prefixes to specify the numbers of atoms of each element. Nomenclature, a collection of rules for naming things, is important in science and in many other situations.This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO 3, and N 2 O 4.The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing … Naming compounds have never been so simple! The name of this acid is sulfuric acid. To denote this distinct chemical property, a mixture of water with an acid is given a name derived from the compound’s name. PLAY. Ionic compounds, just like the name suggests, are made of ions, which are charged particles formed when electrons are transferred between atoms of … But Cr(VI) is much more toxic and forms compounds that are reasonably soluble in water. "What do you mean?" Use the appropriate naming convention (for ionic or molecular substances) to assign a name to each compound. The anions in these compounds have a fixed negative charge (S2−, Se2− , N3−, Cl−, SO42−, O−2, and F−), and the compounds must be neutral. By the end of this module, you will be able to: Nomenclature, a collection of rules for naming things, is important in science and in many other situations. You should know the Roman numerals for 1 (I), 2 (II), 3 (III), 4 (IV), 5 (V), and 6 (VI). Ionic compounds are made up of a metal cation (named first) and a non-metal anion (named second). Naming basic chemical compounds is essential if you want to succeed in chemistry, since the name of the compound clearly defines what it is. Ions (of either variety) may contain either a single element or more than one element. Note that the definition of acid includes dissolved in water. left of the metalloid staircase), it is a metal and the compound is "ionic.". SURVEY . 10. For example, you may see the words stannous fluoride on a tube of toothpaste. For ionic compounds, start by listing the component ions. 9. In cases like this, the charge of the metal ion is included as a Roman numeral in parentheses immediately following the metal name. See Table 1 in Chapter 4.2 Ionic and Molecular Compounds for the list of common polyatomic ions. b) Because this acid is derived from the sulfate ion, the name of the acid is the stem of the anion name + -ic acid. In ionic compounds, the ions are held together due to electrical attraction, whereas, in molecular compounds, the atoms are held together by the attraction between the atoms due to shared electrons. The rules for organic compounds, in which carbon is the principle element, will be treated in a later chapter on organic chemistry. Some examples are given in Table 1. Give the proper formula for each name. In the environment, chromium exists primarily in either the Cr(III) or Cr(VI) forms. Binary ionic compounds typically consist of a metal and a nonmetal. Naming Covalent Compounds (or "Molecular Compounds") When Given the Formula Covalent compounds, often called "molecular compounds," consist of two non-metals; a non-metal / non-metal pair. Iron typically exhibits a charge of either 2+ or 3+ (see Figure 2 in Chapter 4.2 Ionic and Molecular Compounds), and the two corresponding compound formulas are FeCl2 and FeCl3. Covalent or molecular compounds form when elements shareelectrons in a covalent bond to form molecules. a)  N2O         b)  N2O4         c)  N2O5. For example, in sodium chloride, sodium is the cation element and chlorine is the anion element. November 7, 2020, The Best Types of Chemistry Lectures Oxalic acid, H2C2O4(aq), is found in spinach and other green leafy vegetables. Upgrade to remove ads. 19. Ionic compounds consist of cations (positive ions) and anions (negative ions). These are usually the transition metals. Formulas of Ionic Compounds • If the first element you "see" in the compound is found on the left side of the periodic table (i.e. Greek prefixes are used when naming ionic compounds. This online quiz is intended to give you extra practice in naming compounds, writing formulas and calculating ... Names & formulas Molar Mass (aka formula weight) Both! This is the oxide anion. We have discovered how to change chemical formulae into names of chemicals. nomenclature: system of rules for naming objects of interest, oxyacid: compound that contains hydrogen, oxygen, and one other element, bonded in a way that imparts acidic properties to the compound (ability to release H+ ions when dissolved in water). For example, carbon and oxygen can form the compounds CO and CO2. They argue that the average person consumes too much sodium from his or her diet. The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing polyatomic ions, and one specific, very important class of compounds known as acids – subsequent chapters in this text will focus on these compounds in great detail.
