The Bohr model is the diagram we use today to visualize what an atom looks like.

Orbitals: the space occupied by electrons, also known as shells
This is what Bohr believed:
- Electrons have certain energy levels
- When electrons jump to a different orbital, they release a certain spectrum of light
- Excited states are when the electrons jump into a higher or lower level
- Each element gives off a certain spectrum of light when they are heated
