atoms Question 10

Question: Q. 2. What is the maximum number of spectral lines emitted by a hydrogen atom when it is in the third excited state? $◻$ [O.D. Comptt. I, II, III 2013]

Show Answer

Solution:

Ans. If $n$ is the quantum number of highest energy level, then the total number of possible spectral lines emitted is

$N = \frac{n (n - 1)}{2}$

Here, third excited state means fourth energy level, i.e., $n = 4$

$\begin{matrix} (1) & ∴ N = \frac{4 (4 - 1)}{2} = 6 \end{matrix}$
