The angular momentum of electron revolving in the second orbit of H-atom is '' J·s. The angular mome — Atomic Structure Chemistry Question

💡 Solution & Explanation

Angular momentum $L = n\frac{h}{2\pi}$ depends only on the principal quantum number $n$ and is independent of the atomic number $Z$. For $n=2$ in both cases, $L$ remains $x$ J·s. Therefore, correct answer is A.
