Mn have the maximum number of unpaired electrons which are present in the d-subshell (5 electrons). Hence, Mn exhibits the high number of oxidation states which ranges from +2 to +7.

Why does manganese have multiple oxidation states?

Mn have the maximum number of unpaired electrons which are present in the d-subshell (5 electrons). Hence, Mn exhibits the high number of oxidation states which ranges from +2 to +7.

Does manganese have more than one oxidation state?

Transition metals are well known for having more than one stable oxidation state. manganese has more than any other. In its compounds manganese exhibits oxidation states from +2 to +7. The common oxidation states are +2, +4, and +7, but the less common +3, +5, and +6 states are easily prepared.
