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