which is more stable???Mn3+ or Mn2+???give explaination considering electron configuration for both ions...

Mn2+ 1s2 2s2 2p6 3s2 3p6 3d5
Mn3+ 1s2 2s2 2p6 3s2 3p6 3d4
Half filled orbital is more stable and in Mn2+ there is half filled d orbital so,Mn2+ is most stable

Mn+2 is more stable because it has less electrons than Mn+3.

Mn+2 because it takes electrons out of the 4s level first and you sill have the half full 3d level

Mn 2+. this is because Mn 2+ has a alf filled orbital which is much more stable than a partially filled orbital. hence, more energy is needed for it to ionise.

Mn 1s2 2s2 2p6 3s2 3p6 3d5 4s2
Mn2+ 1s2 2s2 2p6 3s2 3p6 3d5 - half filled d-subshell - stabilized
Mn3+ 1s2 2s2 2p6 3s2 3p6 3d4
