Question

Bohr's model of atoms ______.

Options

• Assumes that the angular momentum of electrons is quantised

• Uses Einstein's photoelectric equation

• Predicts continuous spectrum

• Predicts the same emission spectra for all types of atoms

Answer 1

Bohr's model of atoms assumes that the angular momentum of electrons is quantised.

Explanation:

The Bohr's state that the angular momentum of electrons in orbits is an integral multiple of "nh"/(2pi), where n is the number of shells. A fraction cannot represent angular momentum.
