Ionic Compounds

Binary Ionic Compound

Polyatomic Ionic Compound

Metal present is a transition metal and has multiple charges

Name of metal +name of nonmetal -ide

Use the periodic table to determine the oxidation number then criss-cross the charges to make the compound neutral

Name of metal/ polyatomic ion + name of anion/ polyatomic ion (no change in ending of polyatomic ion name)

Use the periodic table and formula chart to find charge of elements and polyatomic ions and criss-cross if needed to make compound neutral

Name of metal (charge of cation in roman numerals) name of nonmetal + -ide or polyatomic ion

Use the known ions charge to determine the charge of the metal, and then criss-cross to make a neutral compound
