Vedclass · Accepted Answer

Pauli's exclusion principle

Vedclass · Answer

(C) In the given configuration,one orbital contains three electrons (two with parallel spins and one with opposite spin),which is physically impossible as an orbital can hold a maximum of two electrons with opposite spins. According to $Pauli's$ exclusion principle,no two electrons in an atom can have the same set of four quantum numbers. This implies that an orbital can hold a maximum of two electrons,and they must have opposite spins. Since the configuration shows an orbital with three electrons,it violates $Pauli's$ exclusion principle.
