Which of the following quantity for an electron revolving round the H-nucleus is independent to the — Atomic Structure Chemistry Question

💡 Solution & Explanation

From Bohr's postulates, $v = \frac{Ze^2}{2\epsilon_0 nh}$, which does not contain the mass of the electron $m$. Distance $r$, K.E., and P.E. all depend on $m$. Therefore, correct answer is D.
