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

💡 Solution & Explanation

The energy level difference is dominated by transitions that end in the ground state (n_1 = 1). The energy gap between n = 1 and n = 2 is Δ E = 13.6 * (1 - 1/4) = 10.2 eV. Since all other listed transitions end at n_1 = 2 (e.g., n = 7 to n = 2 releases only 3.08 eV), the energy released is maximum for n = 2 to n = 1.
