Question

Which of the following is not true about the Bohr's model of atoms?

• A. It assumes that the angular momentum of electrons is quantized.
• B. It uses Einstein's photoelectric equations.
• C. It predicts continuos emission spectra for atoms.
• D. It predicts the same emission spectra for all types of atoms.

Answer 1

The correct option is A It assumes that the angular momentum of electrons is quantized.

Bohr's model of atom assumes that the angular momentum of electrons is quantized.
i.e. the angular momentum of an electron belonging to a particular orbit is equal to integral multiple of $\frac{h}{2\pi }$

Hence, $\left(A\right)$ is the correct answer.
