Nuclear energy is used for the production of destructive hydrogen or nuclear bombs

The protons and neutrons (nucleons) in the nucleus of each atom are held together by very powerful nuclear forces. An enormous amount of energy is required to tear the nucleon apart Enrico Fermi (1984) discovered that the nucleus can be split by bombarding It with a slow neutron. He discovered that the total mass of the component products is less than the mass of the original materials. The difference in mass (mass defect) is a measured of the nuclear energy released. According to Albert Einstein:

E = Δmc²

E = nuclear energy

Δm = mass defect
