Question

Q.12.State : pauli's exclusion principle and Hund's rule of maximum multiplicity.

Answer 1

Answer:

Hunds Rule of Maximum Multiplicity rule states that for a given electron configuration, the term with maximum multiplicity falls lowest in energy. According to this rule electron pairing in p, d and f orbitals cannot occur until each orbital of a given subshell contains one electron each or is singly occupied.

Pauli Exclusion Principle: no two electrons can be identified by the same set of quantum numbers (i.e. must have. different spins)
