Question

what are the factore responsible for the stability of a half- filled orbitals.

Answer 1

I think it can be explained using quantum mechanics.
The motion of e-s with paired spins are said to be correlated. That is paired e-s move together. but unpaired e-s always remain comparatively. further from each other. As a result of this paired e-s have higher energy and thus lesser stability, which are seen in the case of partially filled orbitals.
But in the case of unpaired e-s, repulsion is lesser and thus are more stable which are seen in the case of half filled orbitals
