Definition & Meaning of Nuclear Reactions
Nuclear reactions refer to processes in which atomic nuclei interact, resulting in the transformation of elements and the release or absorption of energy. These reactions can occur naturally, as in the case of radioactive decay, or can be induced artificially, such as in nuclear reactors or particle accelerators. The primary types of nuclear reactions include fusion, fission, and radioactive decay.
In fusion, two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. This is the reaction that powers the sun and other stars. Fission, on the other hand, involves the splitting of a heavy nucleus into lighter nuclei, accompanied by the release of energy. This process is utilized in nuclear power plants and atomic bombs. Radioactive decay is a spontaneous process where unstable nuclei lose energy by emitting radiation, transforming into different elements or isotopes.
