SATHEE: Atoms And Nuclei Question 121

Atoms And Nuclei Question 121

Question: In hydrogen atom, when electron jumps from second to first orbit, then energy emitted is [AIEEE 2002]

Options:

A) ? 13.6 eV

B) ? 27.2 eV

C) ? 6.8 eV

D) None of these

Show Answer

Answer:

Correct Answer: D

Solution:

$E_{n_{1} \to n_{2}} = - 13.6 [\frac{1}{n_{2}^{2}} - \frac{1}{n_{1}^{2}}]; n_{1} = 2 & n_{2} = 1$
$\Rightarrow E_{I I} \to E_{I} = - 13.6 \times \frac{3}{4} = - 10.2 e V$
