Question

mn2+ is more stable than mn3+ why​

Answer 1

Answer:

Mn2+ is more stable than Mn3+ due to the stable electronic configuration ofMn2+ because of half filled d-orbital. Fe3+ is more stable than Fe2+ because Fe3+ has exactly half filled d- orbitals which give the stability to Fe3+ while Fe2+ has 3d6 electronic configuration

Answer 2

Answer:

hii dear,

See ,

The electronic configuration of Mn2+ is [Ar] 18 3d5

Mn3+ is [Ar] 18 3d4

So Mn2+ has half filled d -orbital .

Half filled and completely filled configuration are more

stable. They requires more energy to loose an electron

from their outermost shell .

hope it will help u .

thank u
