MORE STABLE IS Fe 3+ because we know that metals loose their electrons to become stable.

IT MEANS THAT NO. OF LOOSE ELECTRON IS DIRECTLY PROPORTIONAL TO STABILITY OF ELECTRONS.
SINCE Fe 3+ has donated 3 electrons and Fe+2 has donated 2 electrons.
Hence Fe 3+ is more stable

$\mathcal\huge{\boxed{Fe2+ and Fe 3+ which is more stable?}}$
1.Half filled and full filled orbitals are more stable than others.
2.The electronic configuration of Fe(26)
=1s2 2s2 2p6 3s2 3p6 4s2 3d6
3. When d subshell gets filled up the nucleus attracts it closer and the 4s2 becomes outermost orbital and thus the first two electrons will be removed from 4s2 and not 3d6.
4.The electronic configuration of Fe2+ = 1s2 2s2 2p6 3s2 3p6 3d6 4s0
5.The electronic configuration of Fe3+ = 1s2 2s2 2p6 3s2 3p6 3d5 4s0
6. Therefore by comparing both Fe3+ ion is more stable due to the more stability of half filled orbital.[tex][/tex]
