Vedclass · Answer

(C) According to the rules of quantum numbers: $1$. The principal quantum number $n$ can be any positive integer $(1, 2, 3, \dots)$. $2$. The azimuthal quantum number $l$ can have values from $0$ to $n-1$. $3$. The magnetic quantum number $m$ can have values from $-l$ to $+l$. $4$. The spin quantum number $s$ can only be $+1/2$ or $-1/2$. In option $C$,$l = -1$,which is not possible because $l$ cannot be negative. Therefore,this set of quantum numbers is invalid.
