The K.E. of electron in will be maximum in — Atomic Structure Chemistry Question

💡 Solution & Explanation

Kinetic energy $K.E. = 13.6 \frac{Z^2}{n^2}$ eV. It is inversely proportional to $n^2$. Thus, $K.E.$ is maximum when $n$ is minimum, which is the first orbit ($n=1$). Therefore, correct answer is B.
