What is the oxidation number of Mn in Mn04?

In the anions of oxyacids, oxygen is always assigned an oxidation number of -2. Therefore, in an MnO4-1 anion, manganese must have an oxidation number of +7 to achieve electrical balance for the anion. (There is no neutral compound with the formula MnO4.)
