NEET Physics Hydrogen Atom MCQ Question
Type: MCQ-numerical-Easy-Class 12
What is the energy difference between the ground state and the first excited state (n = 2) of a hydrogen atom?
A
10.2 eV
B
13.6 eV
C
3.4 eV
D
0 eV
Correct Answer
Option A
Detailed Explanation
In the Bohr model, the energy of the first excited state (n = 2) is -3.4 eV. The energy of the ground state (n = 1) is -13.6 eV. The energy difference is 13.6 eV - 3.4 eV = 10.2 eV.
