Worksheet 5 - Naming Ionic Compounds Naming

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.

2 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 Write the chemical names of the following Compounds . 1.

3 Rb3P 17. BaS 18. Al4C3 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.

4 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 Sb3+ Antimony (III) Lead Pb2+ Lead (II) Sb5+ Antimony (V) Pb4+ Lead (IV) Arsenic As3+ Arsenic (III) Manganese Mn2+ Manganese (II) As5+ Arsenic (V) Mn4+ Manganese (IV) Cobalt Co2+ Cobalt (II) Mercury Hg+ Mercury (I) Co3+ Cobalt (III) Hg2+ Mercury (II) Copper Cu+ Copper (I) Nickel Ni2+ Nickel (II) Cu2+ Copper (II) Ni3+ Nickel (III) Gold Au+ Gold (I) Tin Sn2+ Tin (II) Au3+ Gold (III) Sn4+ Tin (IV) Iron Fe2+ Iron (II) Titanium Ti3+ Titanium (III) Fe3+ Iron (III) Ti4+ Titanium (IV)

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 Sb3+ Antimonous Lead Pb2+ Plumbous Sb5+ Antimonic Pb4+ Plumbic Arsenic As3+ Arsenous Manganese Mn2+ Manganous As5+ Arsenic Mn4+ Manganic Cobalt Co2+ Cobaltous Mercury Hg+ Mercurous Co3+ Cobaltic Hg2+ Mercuric Copper Cu+ Cuprous Nickel Ni2+ Nickelous Cu2+ Cupric Ni3+ Nickelic Gold Au+ Aurous Tin Sn2+ Stannous Au3+ Auric Sn4+ Stannic Iron Fe2+ Ferrous Titanium Ti3+ Titaniumous Fe3+ Ferric Ti4+ Titaniumic Example copper chloride CuCl (Cu+) or CuCl2 (Cu2+)

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.
