Heya!!!


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

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

It is known that half-filled and fully-filled orbitals are more stable. Therefore, Mn in (+2) state has a stable d5 configuration. This is the reason Mn2+shows resistance to oxidation to Mn3+. Also, Fe2+has 3d6configuration and by losing one electron, its configuration changes to a more stable 3d5configuration. Therefore, Fe2+ easily gets oxidized to Fe+3 oxidation state.
