NEET Physics Hydrogen Atom MCQ Question
Type: MCQ-numerical-Medium-Class 12
What is the energy in eV of an electron in the second orbit (n=2) of a hydrogen atom according to the Bohr model?
A
-3.4 eV
B
-6.8 eV
C
-1.7 eV
D
-13.6 eV
Correct Answer
Option A
Detailed Explanation
In the Bohr model, the energy of an electron in the nth orbit is given by E_n = -13.6/n^2 eV. For n=2, E_2 = -13.6/4 = -3.4 eV.
