NEET Physics Hydrogen Atom MCQ Question
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?
The ground state energy of the electron is -13.6 eV.
The energy required to remove an electron from the ground state is 0 eV.
An electron cannot exist in the continuum of energy states above E = 0 eV.
The energy levels above E = 0 eV are discrete and not continuous.
Correct Answer
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.
