Question

A collection of hydrogen atoms absorbs energy such that an electron reaches $n=5$. If all electrons eventually jump to the ground state without emitting any line in the Balmer series, the number of possible unique spectral radiations is:

Answer: D

💡 Solution & Explanation

Transitions skipping $n=2$ entirely. Permitted paths avoid landing on $n=2$. Lines possible: $5\to4$, $5\to3$, $5\to1$, $4\to3$, $4\to1$, $3\to1$. Total = 6 unique lines emitted without touching $n=2$.
