The energy different will be minimum for which of the following energy levels of H-atom? — Atomic Structure Chemistry Question

💡 Solution & Explanation

The energy spacing between adjacent principal quantum levels in hydrogen decreases as n increases. Evaluating: (a) Δ E(2->3) = -1.51 - (-3.40) = 1.89 eV. (b) Δ E(3->4) = -0.85 - (-1.51) = 0.66 eV. (c) Δ E(1->2) = -3.4 - (-13.6) = 10.2 eV. Thus, the energy difference is minimum for n = 3 and n = 4.
