Which transition in the hydrogen atom emits the largest amount of energy?
A$n = 5 \to n = 4$
B$n = 2 \to n = 1$
C$n = 3 \to n = 2$
D$n = \infty \to n = 1$
Answer & Solution
Correct answer: D. $n = \infty \to n = 1$
Energy released $= E_{n_1} - E_{n_2}$. Maximum gap is from $n = \infty$ (E = 0) to $n = 1$ ($E = -13.6\,eV$). All other listed transitions release less.
