Question #4ff12

Answer 1

It's actually +7.

The manganese (VII) ion gets its name from the fact that manganese is in a +7 oxidation state.

You'll find the manganese (VII) ion as part of the permanganate polyatomic ion, `MnO_4^(-)`. As you would predict, the +7 oxidation number that manganese has in the permanganate ion makes it a very strong oxidizer.
