Nuclear fission is a process in which the nuclei of heavy atoms, such as uranium or plutonium, split into two smaller nuclei when bombarded by neutrons.
This division releases a large amount of energy in the form of heat and radiation.
In a controlled chain reaction, the released neutrons can collide with other nuclei, generating more divisions and releasing more energy.
Nuclear fission is used in nuclear power plants to produce electricity, harnessing the energy released in the process of splitting atoms.
