Manganese shows variable oxidation states. Give reasons. – InterviewSolution

1.	Manganese shows variable oxidation states. Give reasons.
Answer» Manganese (₂₅Mn) has electronic configuration. ₂₅Mn [Ar]¹⁸3d⁵4s². Mn has stable half-filled d-subshell. Due to a small difference in energy between 3d and 4s-orbitals, Mn can lose or share electrons from both the orbitals, hence shows variable oxidation states. Mn shows oxidation states ranging from + 2 to + 7.
