NEET Physics Hydrogen Atom MCQ Question

Type: MCQ-diagram based-Medium-Class 12

Consider a diagram depicting the energy level diagram for the hydrogen atom, with horizontal lines indicating allowed energy states. Which of the following statements about the energy levels is correct?

Question diagram
A

The ground state energy of the electron is -13.6 eV.

B

The energy required to remove an electron from the ground state is 0 eV.

C

An electron cannot exist in the continuum of energy states above E = 0 eV.

D

The energy levels above E = 0 eV are discrete and not continuous.

Correct Answer

Option A

Detailed Explanation

The energy level diagram shows that the ground state energy of an electron in a hydrogen atom is -13.6 eV. To ionize the hydrogen atom, 13.6 eV of energy must be supplied from the ground state. The continuum of energy states exists above E = 0 eV, where the electron is free.
