Question

half filled and completely filled orbital have extra stability why​

Answer 1

Answer:

The half-filled and fully-filled orbitals are more symmetrical than any other configuration and symmetry leads to greater stability. The electrons present in the different orbitals of the same sub-shell can exchange their positions. Each such exchange leads to the decrease in energy known as Exchange Energy.
