Question

Which of the following postulates of the Bohr model led to the quantization of energy of the hydrogen atom?

• A. The electron goes around the nucleus is circular orbits.
• B. The angular momentum of the electron can only be an integral multiple of $h/2\pi$
• C. The magnitude of the linear momentum of the electron is quantized.
• D. Quantization of energy is itself a postulate of the Bohr model.

Answer 1

Answer: (B)

The angular momentum of the electron can only be an integral multiple of $h/2\pi$

Answer 2

Bohr’s quantization condition of angular

momentum i,e, $L = n\frac{h}{2\pi}$ led to the quantization of energy .
