Electrons have set orbits around the nucleus, whose energies depend on size. When an electron moves between orbits radiation is either absorbed or emitted.
- Electrons orbit the nucleus in orbits that have a set size and energy.
- The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
- Radiation is absorbed or emitted when an electron moves from one orbit to another.
