Nuclear Reactions

Nuclear reactions involve changes in the nucleus of an atom and typically result in the release of large amounts of energy. There are two main types of nuclear reactions: fission and fusion.

Fission

Fission is the process of splitting a heavy nucleus into two smaller nuclei. This process is accompanied by the release of a large amount of energy and the production of additional neutrons. Fission is the process used in nuclear power plants to generate electricity.

Fusion

Fusion is the process of combining two light nuclei to form a heavier nucleus. This process also releases a large amount of energy and is the process that powers the sun and other stars. Fusion has the potential to provide a nearly limitless source of energy, but it is currently very difficult to achieve on Earth due to the high temperatures and pressures required.
