Question

What do you mean by maximum multiplicity?

Answer 1

Answer:

During the filling of orbitals the maximum number of unpaired electrons is achieved and hence the maximum total spin state. This is the maximum multiplicity.

Answer 2

Answer:

Maximum Multiplicity

Explanation:

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 . The rule states that for a given electron configuration , the lowest energy term is the one with the greatest value of spin multiplicity . This implies that if two or more orbitals of equal energy are available , electrons will occupy them singly before filling them in pairs . 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 .
