1. 6.6 – NOTES Naming Ionic Compounds

2. 3. Naming ionic compounds
a. Monatomic cations are known by their name. For example, Na+ is sodium.
b. Monatomic anions have the ending “ide,” which means negative. For example, O-2 is known as oxide. Polyatomic ions have their normal names.
c. Cations with more than one oxidation state: the oxidation state must be specified.

3. Traditional naming: makes use of Latin name; uses suffix –ic for higher oxidation state and –ous for lower oxidation state of the metal
Stock system: this is one to know; makes use of English name; uses Roman numerals to denote the oxidation state

4. Examples:
RbNO2
rubidium nitrite
CuSO4
cupric sulfate
copper (II) sulfate

5. Fe(HSO4)2
ferrous bisulfate
iron (II) bisulfate
(NH4)3PO4
ammonium phosphate

6. Al2(SO3)3
aluminum sulfite
Pb(CO3)2
lead (IV) carbonate
Plumbic carbonate

7. FeCl3
ferric chloride
iron (III) chloride
SnI4
stannic iodide
tin (IV) iodide
