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 \hbar), where is a positive integer and (\hbar) is the reduced Planck's constant.
4. The radius of the electron's orbit in a hydrogen atom decreases as the electron moves to higher energy levels.
Which of the above statements are correct?
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 \propto n^2)).
