The angular momentum of electron revolving round nucleus of H-atom is directly proportional to — Atomic Structure Chemistry Question

💡 Solution & Explanation

Angular momentum $L \propto n$. The radius $r \propto n^2$, which implies $n \propto r^{1/2}$. Substituting $n$, we get $L \propto r^{1/2}$. Therefore, correct answer is B.
