NEETPhysicsAtomic Physics
Consider the following statements about the Bohr model of the hydrogen atom: 1. The energy levels of the hydrogen atom are quantized, and electrons can only occupy these discrete energy levels. 2. The electron in a hydrogen atom revolves in a circular orbit around the nucleus due to the electrostatic force between the nucleus and the electron. 3. The angular momentum of the electron is quantized and is given by (L=n
Options
- A1, 2, and 3 only
- B1, 2, and 4 only
- C2, 3, and 4 only
- DAll of the above
Correct answer
A. 1, 2, and 3 only
Step-by-step solution
- Statement 1 is correct: Bohr proposed that the energy levels in atoms are quantized. - Statement 2 is correct: The electron moves in a circular orbit due to the electrostatic attraction between the electron and the nucleus. - Statement 3 is correct: The angular momentum is quantized as per Bohr's model. - Statement 4 is incorrect: The radius of the orbit increases as the electron moves to higher energy levels (i.e., (r n^2 )).
