Answer 2

↪️Hund's Rule↩️

Hund's Rule of maximum multiplicity

There are 3 statement given under Hund's Rule :-

1. The spin of electron must be same until the subshell is half filled.

2. Pairing of electrons must be restricted until the subsoil is half filled.

3. Symmetry symmetry leads to stability.
