Vedclass · Answer

(D) According to the $Pauli$ exclusion principle,any single orbital can hold a maximum of $2$ electrons with opposite spins.The quantum numbers $n=4$ and $l=3$ specify a $4f$ subshell,which contains $7$ distinct orbitals.However,the question asks for the maximum number of electrons in an orbital (singular),not the entire subshell.Therefore,regardless of the values of $n$ and $l$,any single orbital can accommodate a maximum of $2$ electrons.

The maximum number of electrons present in an orbital with $n=4, l=3$ is
