Vedclass · Answer

(A) For a set of quantum numbers to be valid,the following rules must be satisfied:$1$. $n$ is a positive integer $(1, 2, 3, \dots)$.$2$. $l$ can have values from $0$ to $n-1$.$3$. $m$ can have values from $-l$ to $+l$ (including $0$).$4$. $s$ can be $+1/2$ or $-1/2$.Checking the options:$(A)$ $n=3, l=2, m=2, s=+1/2$: Here $l $(B)$ $n=3, l=4$: Invalid because $l$ must be less than $n$.$(C)$ $n=4, l=0, m=2$: Invalid because $|m|$ must be $\le l$ $(2 
ot\le 0)$.$(D)$ $n=4, l=4$: Invalid because $l$ must be less than $n$.
