Hund's rule of maximum multiplicity is a rule based on observation of atomic spectra, which is used to predict the ground state of an atom or molecule with one or more open electronic shells.
Hund's rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
Forexample..
For example, a nitrogen atom's electronic configuration would be 1s22s22p3. The same orbital will be occupied by the two 2s electrons although different orbitals will be occupied by the three 2p electrons in accordance to Hund's rule.
