Type: MCQ-numerical-Hard-Class 12

What is the energy difference between the ground state and the first excited state of a hydrogen atom?

A

10.2 eV

B

13.6 eV

C

4 eV

D

5 eV

Correct Answer

Option A

Detailed Explanation

The energy of the ground state (n=1) is -13.6 eV and for the first excited state (n=2) is -3.4 eV. The difference is 13.6 - 3.4 = 10.2 eV.
