The Bohr model of atoms

1. predicts the same emission spectra for all types of atoms
2. assumes that the angular momentum of electrons is quantised
3. uses Einstein’s photoelectric equation
4. predicts continuous emission spectra for atoms

Correct answer: assumes that the angular momentum of electrons is quantised

Solution

The Bohr model assumes that the angular momentum of electrons is quantized, which is a key postulate of the model. This quantization explains the discrete energy levels and the emission spectra of atoms.
