If an electron in H-atom jumps from one orbit to other, its angular momentum doubles. The distance o — Atomic Structure Chemistry Question

💡 Solution & Explanation

Angular momentum $L \propto n$. If $L$ doubles, $n$ becomes $2n$. Since radius $r \propto n^2$, the new radius $r' \propto (2n)^2 = 4n^2$. The distance becomes 4 times. Therefore, correct answer is B.
