The time period of revolution of electron in H-atom is directly proportional to — Atomic Structure Chemistry Question

💡 Solution & Explanation

The time period $T \propto n^3$. Since the radius $r \propto n^2$, we have $n \propto r^{1/2}$. Substituting this gives $T \propto (r^{1/2})^3 = r^{3/2}$. Therefore, correct answer is C.
