Electronic configuration of Mn2+ is [Ar]18 3d5 and Electronic configuration of Fe2+ is [Ar]18 3d6.

As the half-filled and fully-filled orbitals are more stable, Mn in (+2) state has the stable d5 configuration.

Mn2+ provides resistance to the oxidation to the Mn3+.

Fe2+ has the 3d6 configuration and its configuration changes after it loses 1 electron and it turns to the 3d5 configurations which is more stable.

As a result, Fe2+ becomes oxidized easily to the Fe+3 states.
