Question

state hund's rule of maximum multiplicity
​

Answer 1

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.

State Hund’s Rule

It states that:

It states that:1. In a sublevel, each orbital is singly occupied before it is doubly occupied.

It states that:1. In a sublevel, each orbital is singly occupied before it is doubly occupied.2. The electrons present in singly occupied orbitals possess identical spin.
