Question

Electrons occupy the degenerate orbitals with parallel spins. How can you justify this statement with respect to stability?

Answer 1

1. Degenerate orbitals are orbitals that have equal energies belonging to the same energy level.
2. If an electron occupies one of the orbitals, the next electron necessarily takes the same spin and enters into the other vacant orbital instead of pairing up with the electron in the 1^st orbital.
3. The electrons always repel each other due to their same charge. If they rotate around their axis in the same direction, they will have a similar magnetic moment and they will further repel each other and maintain maximum distance among each other which gives rise to the maximum stability.
