Ionic Nomenclature

Cation uses its original name (e.g. Sodium)
If the anion has no extra oxygen (e.g. Cl, N, O, etc.), change suffix to -ide (e.g. Cl becomes Chloride)
If the anion has standard number of oxygen (e.g. \(PO_4\) ), change suffix to -ate (e.g. \(PO_4\) becomes Phosphate)
If the anion has one less than the standard number of oxygen (e.g. \(NO_2\)), change suffix to -ite (e.g. \(NO_2\) becomes Nitrite)
If the anion has two less than the standard number of oxygen (e.g. \(NO\)), change the prefix to hypo- and the suffix to -ite (e.g. \(NO\) becomes Hyponitrite)
