Question

The Bohr model of atoms:

• A. uses Einstein's photo electric equation
• B. predicts continuous emission spectra for atoms
• C. predicts the same emission spectra for all types of atoms
• D. assumes that the angular momentum of electrons is quantized

Answer 1

The correct option is D assumes that the angular momentum of electrons is quantized

Bohr model of an atom states that only those orbits are allowed where angular momentum of electron are integral multiple of $nh/2\pi$. These orbits have quantized energy and angular momentum associated with electron.

The model can be applied to hydrogen or hydrogen-like atoms to explain their line emission spectrum.

option D is correct.
