1 Naming Compounds

2 Binary Compounds 1.Name the cation (positive ion) first. 2.Name the anion (negative ion) changing the ending to –ide. ** No ending change for polyatomic ions Example: CaBr 2 calcium bromide NaOHsodium hydroxide

3 Naming Compounds with Roman numerals Name using binary compound rules. Determine the oxidation number of anion. Multiply the oxidation number by the subscript of the anion. Divide the product by the subscript of the cation. Example: W 2 O 3

4 Molecular Compounds Naming 1.Name the cation adding a prefix IF there is more than one. 2.Name the anion adding a prefix and change the ending to –ide. Examples: CS 2 carbon disulfide P 4 O 10 tetraphosphorus decoxide OneMono- TwoDi- ThreeTri- FourTetra- FivePenta- SixHexa- SevenHepta- EightOcta- NineNona- TenDeca- Prefixes

5 HYDRATES EXAMPLES: Na 2 CO 3 7H 2 O Sodium carbonate heptahydrate Ga 2 O 3 H 2 O Gallium (III) oxide monohydrate 1.Name the compound just as you name binary compounds. 2.Indicate the number of water molecules per formula unit using prefixes.
