How are polyatomic ions named?
Well, usually the characterizing names must simply be learned by usage...
Clearly, this is a selection....the ions that have the central atom in its maximum oxidation state, i.e.
ate indicates that the ion is oxidized to the normal oxidation state.
ite indicates that the ion is oxidized at less than the normal oxidation state.
Hyper ate means the oxidation state is more than normal
Hyper Chlorate =
Hypo its means the oxidation state is less than normal
Pay attention to the endings of the polyatomic ions. The prefixes and suffixes gives clues of how the polyatomic ions are named.
