For which transition in H-atom, the amount of energy released will be maximum? — Atomic Structure Chemistry Question

💡 Solution & Explanation

The energy gap between $n=1$ and $n=2$ is $10.2$ eV, which is greater than any transition terminating at $n=2$ (the entire Balmer series spans from 1.89 eV to 3.4 eV). Thus $n=2 \to 1$ releases the most energy. Therefore, correct answer is C.
