Question

Give reason why half filled or fully filled orbitals provide more stability to the molecules?

Open in App

Solution

The exactly half-filled and fully filled orbitals have greater stability than other configurations. The reason for their stability are symmetry and exchange energy. The electrons present in the different orbitals of the same sub-shell can exchange their positions.
