Nuclear Reactions

Nuclear reactions involve changes in the nucleus of atoms, resulting in the formation of different elements or isotopes. These reactions are the basis for processes such as nuclear fission, nuclear fusion, and radioactive decay.

Nuclear Fission

Nuclear fission is the process where the nucleus of an atom splits into two smaller nuclei, along with the release of a large amount of energy. This process is the basis for nuclear power plants and nuclear weapons.

Nuclear Fusion

Nuclear fusion involves the combination of two atomic nuclei to form a heavier nucleus. This process powers the sun and other stars, and is being researched as a potential future energy source on Earth.

Radioactive Decay

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation, resulting in the transformation of the nucleus into another element or isotope.
