The ratio of the difference in energy between the 1st and 2nd Bohr orbit to that between the 2nd and — Atomic Structure Chemistry Question

💡 Solution & Explanation

Energy diff $E_2-E_1 \propto (1/1 - 1/4) = 3/4$. Energy diff $E_3-E_2 \propto (1/4 - 1/9) = 5/36$. Ratio = $(3/4) / (5/36) = (3 \times 36) / (4 \times 5) = 27/5$.
