(long answers) state hund's rule of maximum multiplicity with suitable ex​

Answer 1

Explanation:

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. For example, for boron through neon, the electron filling order of the 2p orbitals follows Hund's Rule. Hund's Rule states that: Every orbital in a sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbitals have the same spin
