Match list I with list II — Atomic Structure Chemistry Question

💡 Solution & Explanation

(A) The total number of subshells (values of $l$) for a given shell $n$ is equal to $n$ (Matches S). (B) The allowed values of $l$ range from $0$ to $(n - 1)$ (Matches P). (C) For a given $l$, the total number of magnetic quantum number ($m$) values is $2l + 1$ (Matches R). (D) The actual allowed values of $m$ range from $+l$ down to $-l$ (Matches Q). Therefore, correct answer is A-S; B-P; C-R; D-Q.
