Question

States the following law : Hund's Rule

Answer 1

◆Hund's rule of maximum multiplicity.

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.

Answer 2

Every orbital in a Sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbital have the same spin (to maximize total spin)
