Naming Compounds – Review
Name: ________________________
(pearsongreatpath.wikispaces.com)
Ionic Compounds = 1) Metal Cation + Non-Metal Anion, 2) Net Charge =0, 3) No Prefixes
--4) Metals with more than one stable charge need roman numerals (never 1A, 2A)
--5) –ide refers to a monoatomic anion, -ate & -ite are polyatomic ion
