When these atoms are hit by a neutron, they might cut up into two smaller atoms-and not at all times the identical two forms of smaller atoms-and in the method release vitality and more neutrons. Many of the smaller atoms formed by this process are unstable and because of this launch radioactivity within the form of gamma rays, alpha particles, or beta particles.
