Key concepts
3 concepts
- 1
Bohr extended energy quantization to the atom, stating that an electron can only inhabit certain energy levels at fixed distances from the nucleus.
- 2
An electron transitions between energy levels by absorbing or emitting a photon with energy equal to the difference between the energy levels.
- 3
The Balmer series contains transitions that generate photons of visible light, and each element has a unique emission spectrum due to its unique nucleus and energy levels.

Practice
3 questions
According to Bohr's model, why don't electrons collide with the nucleus of an atom?
Explain how the Bohr model accounts for the emission spectra of different elements.
