Electronic configuration of Mn^{+2}  = [AR]^{18} 3d^{5}and electronic configuration of Fe^{+2}  = [AR]^{18} 3d^{6}
since full and half filled orbitals r more stable then  Mn^{+2}  is more stable then Fe^{+2}  because it  has half filled orbitalad since Fe^{+2} releases 1 more electron it also gets stable.
