NEET Physics Hydrogen Atom MCQ Question
Which of the following statements about the hydrogen atom are correct?
The total energy of the electron in the hydrogen atom is negative, indicating it is bound to the nucleus.
The electrostatic potential energy of the electron is positive, suggesting the electron is free.
The kinetic energy and potential energy of the electron are equal in magnitude but opposite in sign.
The electron in a hydrogen atom can follow a closed orbit only if its total energy is positive.
Correct Answer
Detailed Explanation
The total energy of the electron in a hydrogen atom is negative, which shows it is bound to the nucleus. The potential energy is negative, indicating attraction, while the kinetic energy is positive. Option B is incorrect because the potential energy is negative, and D is wrong as a positive total energy would imply the electron is not bound.
