An electron that has the quantum numbers and — Atomic Structure Chemistry Question

💡 Solution & Explanation

For $n=3$, the permissible values of $l$ are 0, 1, and 2. The magnetic quantum number $m$ must satisfy $-l \le m \le +l$. For $m=2$ to be valid, $l$ must be at least 2. Given the restriction of $n=3$, $l$ must exactly be 2. Therefore, correct answer is D.
