Write the different oxidation states of manganese. Why +2 oxidation st

1.	Write the different oxidation states of manganese. Why +2 oxidation state of manganese is more stable?OR Explain why Mn2+ ion is more stable than Mn3+?
Answer» Oxidation states of Mn: +2, +3, +4, +5, +6 and +7. Electronic configuration of Mn:1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s² Due to the presence of half filled ‘d’ orbital, the +2 oxidation state of manganese is more stable.

Write the different oxidation states of manganese. Why +2 oxidation state of manganese is more stable?OR Explain why Mn2+ ion is more stable than Mn3+?

Answer»

Oxidation states of Mn: +2, +3, +4, +5, +6 and +7.

Electronic configuration of Mn:1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s²

Due to the presence of half filled ‘d’ orbital, the +2 oxidation state of manganese is more stable.
