Nuclear fission is the process in which a heavy nucleus, such as uranium-235 or plutonium-239, splits into two smaller nuclei, releasing a significant amount of energy. This process is harnessed in nuclear power plants to generate electricity. The energy released during fission is due to the binding energy of the nucleus, which is converted into kinetic energy of the fission fragments and subsequently into heat.
Nuclear Fusion
Nuclear fusion, on the other hand, involves the combining of light nuclei, such as hydrogen isotopes, to form a heavier nucleus. This process powers the sun and other stars. Fusion reactions release even more energy than fission reactions, but achieving controlled fusion on Earth has proven to be a significant challenge.
