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 in 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

The correct option is B The angular momentum of the electron can only be an integral multiple of $h/2\pi$.

$\begin{array}{c}\text{Quantization of of energy of the}\\ \text{hydrogen atom is lead by}\\ \text{angular momentum of the electron can}\\ \text{only be an integral multiple of}\\ h/2\pi .\end{array}$
