Vedclass · Answer

(A) For a valid set of quantum numbers,the following rules must be satisfied: $1$. $n$ (principal quantum number) must be a positive integer $(1, 2, 3, ...)$. $2$. $l$ (azimuthal quantum number) can have values from $0$ to $n-1$. $3$. $m$ (magnetic quantum number) can have values from $-l$ to $+l$ including $0$. In option $A$,$n = 1$. The allowed value for $l$ is only $0$ $(n-1 = 1-1 = 0)$. Since $l = 2$ is given,this set is invalid because $l$ cannot be greater than or equal to $n$.
