Nuclear Binding Energy and Reactions

What holds a nucleus together, and how nuclei can release energy.

Binding Energy

The binding energy of a nucleus is the energy required to break it apart into its individual protons and neutrons — it is a measure of the nucleus's stability.

Nuclear Fission and Fusion

  • Fission — a heavy nucleus splits into lighter nuclei, releasing energy
  • Fusion — light nuclei combine into a heavier nucleus, releasing energy (the process that powers the Sun)
