NEET Physics Hydrogen Atom MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about the hydrogen atom is correct?
A
The electron in a hydrogen atom primarily exists in the ground state at room temperature.
B
A hydrogen atom can only be ionized by providing exactly 13.6 eV of energy.
C
Electrons in a hydrogen atom can have any total energy below E = 0 eV.
D
The ground state of a hydrogen atom has a total energy of 0 eV.
Correct Answer
Option A
Detailed Explanation
The electron in a hydrogen atom spends most of its time in the ground state at room temperature, as stated in the context. Option B is incorrect because more than 13.6 eV can also ionize the atom, C is incorrect since total energy cannot be below E = 0 eV, and D is incorrect as the ground state energy is -13.6 eV.
