Question

half filled and completely filled orbitals have extra stability. why?​

Answer 1

Answer:

The orbitals in which the sub-shell is exactly half-filled or completely filled are more stable because of the symmetrical distribution of electrons. Exchange energy: The electrons which are there in degenerate orbitals have a parallel spin and tend to exchange their position......

HOPE IT HELPS UUUHHH...

THANK UUH...

Answer 2

Answer:

• Symmetrical distribution of electrons

Symmetry leads to stability.

• Exchange Energy
