Why is the angular momentum has no significance in calculating the magnetic moment of d block elements

The angular momentum of d block elements has no significance in calculating their magnetic moment due to the following reasons:

1. Hund's rule: According to Hund's rule, when filling the d orbitals, electrons prefer to occupy separate orbitals with parallel spins before pairing up. This results in Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
