Electron Arrangements

Physics: AQA GCSE Higher, topic 3.1.6

Electron Arrangements

Electrons are arranged in shells around a nucleus. Each shell has a different energy level. When an atom absorbs or emits electromagnetic radiation, its electron arrangements can change.

Absorb radiation

Absorb radiation

  • When atoms absorb electromagnetic radiation, electrons move to a higher energy level further away from the nucleus.
Emit radiation

Emit radiation

  • When atoms emit electromagnetic radiation, electrons can drop to a lower energy level, closer to the nucleus.
