The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.

Hunds Rule :
It states that pairing of electron doesn't take place until all the orbitals in the same shell are singly filled.
Exceptional Electronic Configuration:
Half filled and fully filled electronic configuration is always extra stable due to symmetry and high exchange energy as a result in both chromium and copper one electron from 4s orbital is transferred into 3D orbital to attain extra stable half filled and freely filled electronic configuration respectively.
- Fully filled and half filled orbitals are extra stable than that of other variable fillings of electrons.
