Answer:
Hund's rule
Explanation:
Hund's rule is defined as the rule whose first rule in the chemistry says that, for a given electronic configuration, the term which posses lowest energy has maximum multiplicity. The multiplicity is defined as the tem 2S+1, where S is the total spin angular momentum.
Therefore, the term which has lowest energy that term posses maximum number of S.
Hund's rule of maximum multiplicity: Electron present in same energy orbitals firstly they completed half orbit than start pairing.
Therefore, the energy of lowest configuration for an atom is the one having the maximum number of unpaired electron which is allowed by the Pauli principle in a particular set of degenerate orbit is called Hund's rule.
