Vedclass · Answer

(D) For a set of quantum numbers to be valid,they must satisfy the following rules:$(i)$ $l$ must be in the range $0$ to $n-1$.$(ii)$ $m_{l}$ must be in the range $-l$ to $+l$.$(iii)$ $m_{s}$ must be either $+1/2$ or $-1/2$.Evaluating the options:$A$: $m_{s}=0$ is invalid.$B$: $m_{l}=-3$ is invalid because for $l=1$,$m_{l}$ can only be $-1, 0, 1$.$C$: $l=3$ is invalid because for $n=3$,$l$ can only be $0, 1, 2$.$D$: $n=2, l=1, m_{l}=-1, m_{s}=1/2$ satisfies all conditions.
