Expert Answer:

The disintegration of an atomic nucleus into two or more smaller fragments. Fission is a form of radioactivity and, like other forms, may be spontanious or induced by irraditiation. In fission, nuclei usually disintegrate to form two fragments of roughly comparable mass number along with several neutrons.For examble the neutron-induced fission of U 235  could yield Kr90 and Ba143

          235U92 +1n0→90Kr36 +143Ba56 = 31n0 +energy
