Question

what is hund'srule 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.

Answer 2

Answer:

According to hund,

Before the double occupation of any orbital, every orbital in the sub level is singly occupied.

For the maximization of total spin, all electrons in a single occupancy orbital have the same spin.
