8.3 Manganese (Z = 25) exhibits the largest number of oxidation states. This is because its electronic configuration is 3d54s2.
Because it has the maximum number of electrons (5 d electrons and 2s electrons) to easily lose and share.
Therefore, it can exhibit an oxidation state of +2 to +7. The compounds are as follows:
Mn (0) as Mn (s), Mn (II) as MnO, Mn (II, III), Mn etc.
