The two processes by which nuclear energy is released are nuclear fission and nuclear fusion.
Nuclear fission involves splitting the nucleus of an atom into two smaller nuclei, releasing a large amount of energy in the process. This is typically achieved by bombarding a radioactive material with a neutron, which causes the nucleus to become unstable and split apart. This process is used in nuclear reactors to generate electricity.
Nuclear fusion involves combining the nuclei of two atoms to form a larger nucleus, also releasing a large amount of energy in the process. This process occurs naturally in the sun and other stars, where the immense heat and pressure cause hydrogen nuclei to fuse into helium. Scientists are currently researching nuclear fusion as a potential source of clean, sustainable energy on Earth.
