1 Worksheet 5 - Naming Ionic Compounds Part 1 (Binary compounds with Group 1, 2 or 13 metals) Binary compounds: have only two kinds of elements, if there are three or more it is not a binary compound. Naming 1. Metal goes first and you get the name directly from the periodic table. 2. Non-metal goes second. The ending changes to ide Name of element Name at end of compound Name of element Name at end of compound Fluorine Fluoride Oxygen Oxide Chlorine Chloride Sulfur Sulfide Bromine Bromide Nitrogen Nitride Iodine Iodide Phosphorus Phosphide Write the chemical formula for each of the following. 1. lithium chloride 2. beryllium chloride 3. sodium oxide 4. potassium sulfide 5. magnesium phosphide 6. aluminum fluoride 7. calcium nitride 8. magnesium oxide 9. beryllium nitride 10. potassium carbide 11. potassium nitride 12. potassium fluoride 13. aluminum nitride 14. sodium fluoride 15. calcium carbide 16. barium bromide 17. francium phosphide 18. gallium sulfide

2 Write the chemical names of the following compounds. 1. LiF 2. Li2O 3. AlP 4. NaCl 5. K2S 6. Ca3N2 7. MgO 8. BeS 9. Ca2C 10. Li4C 11. AlF3 12. KBr 13. Ga2O3 14. CsI 15. SrAt2 16. Rb3P 17. BaS 18. Al4C3

3 Worksheet 6 - Naming Ionic Compounds Part 2 (Binary compounds with Group 3-12 metals) Naming (STOCK SYSTEM) 1. Metal goes first and you get the name directly from the periodic table. 2. Immediately after the metal in brackets write the charge of the metal ion in roman numerals. 3. Non-metal goes second. The ending changes to ide The metals in Groups 3 12 can have more then one charge on the ion (polyvalent ions) so when you name them you have to add in the charge of the metal ion by using roman numerals. This method of naming is called the stock system and is used only for the polyvalent ions. There is another method of naming the polyvalent ions, which we will look at in part 3 of naming ionic compounds. Element Cations Name of Cation Element Cations Name of Cation Antimony Sb 3+ Antimony (III) Lead Pb 2+ Lead (II) Sb 5+ Antimony (V) Pb 4+ Lead (IV) Arsenic As 3+ Arsenic (III) Manganese Mn 2+ Manganese (II) As 5+ Arsenic (V) Mn 4+ Manganese (IV) Cobalt Co 2+ Cobalt (II) Mercury Hg + Mercury (I) Co 3+ Cobalt (III) Hg 2+ Mercury (II) Copper Cu + Copper (I) Nickel Ni 2+ Nickel (II) Cu 2+ Copper (II) Ni 3+ Nickel (III) Gold Au + Gold (I) Tin Sn 2+ Tin (II) Au 3+ Gold (III) Sn 4+ Tin (IV) Iron Fe 2+ Iron (II) Titanium Ti 3+ Titanium (III) Fe 3+ Iron (III) Ti 4+ Titanium (IV) Example copper chloride CuCl or CuCl2 Both are copper chloride copper (I) chloride copper (II) chloride Need the charge on copper Write the names of the following compounds. 1. CuO 2. Cu2O 3. Sb2O5

4 4. Sb2O3 5. PbCl4 6. NiBr2 7. AuP 8. Au3P 9. FeO 10. Sn3P4 11. Fe2C 12. Co4C3 13. Hg3N 14. MnS2 15. AsI5 16. SnO 17. Ti2S3 18. TiF4 Write the chemical formulas of the following 1. manganese (IV) oxide 2. arsenic (V) sulfide 3. cobalt (II) chloride 4. antimony (III) bromide 5. iron (II) carbide 6. gold (I) iodide 7. mercury (II) nitride 8. cobalt (III) phosphide 9. nickel (III) oxide 10. titanium (IV) carbide 11. antimony (V) oxide 12. tin (II) fluoride 13. lead (IV) nitride 14. arsenic (V) bromide 15. gold (II) sulfide 16. antimony (V) phosphide 17. copper (I) oxide 18. gold (I) carbide

5 Worksheet 7 - Naming Ionic Compounds Part 3 (Binary compounds with Group 3-12 metals) Naming (CLASSICAL SYSTEM) 1. Metal goes first. Some metals use special names. For all of the metals the ending changes to ous or ic ( ous is for the lower ion of the metal, while ic is for the higher ion of the metal) 2. Non-metal goes second. The ending changes to ide Element Cations Name of Cation Element Cations Name of Cation Antimony Sb 3+ Antimonous Lead Pb 2+ Plumbous Sb 5+ Antimonic Pb 4+ Plumbic Arsenic As 3+ Arsenous Manganese Mn 2+ Manganous As 5+ Arsenic Mn 4+ Manganic Cobalt Co 2+ Cobaltous Mercury Hg + Mercurous Co 3+ Cobaltic Hg 2+ Mercuric Copper Cu + Cuprous Nickel Ni 2+ Nickelous Cu 2+ Cupric Ni 3+ Nickelic Gold Au + Aurous Tin Sn 2+ Stannous Au 3+ Auric Sn 4+ Stannic Iron Fe 2+ Ferrous Titanium Ti 3+ Titaniumous Fe 3+ Ferric Ti 4+ Titaniumic Example copper chloride CuCl (Cu + ) or CuCl2 (Cu 2+ ) Both are copper chloride cuprous chloride cupric chloride Must indicate the charge with ous or ic Write the names of the following compounds. 1. CuO 2. Cu2O 3. Sb2O5 4. Sb2O3 5. PbCl4 6. NiBr2

6 7. AuP 8. Au3P 9. FeO 10. Sn3P4 11. Fe2C 12. Co4C3 13. Hg3N 14. MnS2 15. AsI5 16. SnO 17. Ti2S3 18.

7 Worksheet 8 - Naming Ionic Compounds Part 4 (For compounds that are not binary) There are groups of non-metals that like to stay together and have a total charge these are called polyatomic ions. Naming 1. Metal goes first and all previous rules for the metals apply. 1a) Group 1, 2, 13 metals name directly from periodic table 1b) Group 3 12 metals STOCK SYSTEM name from periodic table plus identify the charge using roman numerals 1c) Group 3 12 metals CLASSICAL SYSTEM ous identifies lower ion and ic identifies higher ion 2. Negative polyatomic ion second and you get the name from the table below. Polyatomic ions Name of Ion formula Name of Ion formula polyatomic ion polyatomic ion Nitrite NO2 - Hydrogen Carbonate HCO3 - Nitrate NO3 - (Bicarbonate) Sulfite SO3 2- Carbonate CO3 2- Sulfate SO4 2- Phosphate PO4 3- Chlorite ClO2 - Acetate C2H3O2 - Chlorate ClO3 - Cyanide CN - Arsenite AsO3 3- Hydroxide OH - Arsenate AsO4 3- Ammonium NH4 + Name the following compounds 1.
