Why is Mn2+ ion more stable than Fe2+ ion?
(Atomic numbers of Mn = 25 and Fe = 26)
उत्तर
Electronic configuration of Mn2+ = [Ar]4s03d5 and Fe2+ = [Ar]4s03d6
Mn2+ ions have half-filled d-orbitals, making them more stable. Fe2+ complexes are slightly less stable since their third orbital contains six electrons.
As a result, they frequently achieve a stable 3d5 structure while losing one electron (from Fe3+).
