Nuclear Fission

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

Process of Nuclear Fission

The process of nuclear fission typically involves bombarding a heavy atomic nucleus, such as that of uranium-235, with a neutron. This causes the nucleus to become unstable and split into two or more smaller nuclei, along with the release of additional neutrons and a large amount of energy in the form of gamma rays and kinetic energy.

Energy Release

The energy released during nuclear fission is due to the conversion of mass into energy, as described by Einstein's famous equation E=mc^2, where E is energy, m is the mass lost during the process, and c is the speed of light. This energy release is harnessed in nuclear power plants to generate electricity.

Applications

Nuclear fission has both peaceful and destructive applications. In nuclear power plants, controlled fission reactions are utilized to generate electricity, providing a significant source of energy. On the other hand, nuclear fission is also the principle behind the explosive power of nuclear weapons.
