Question

The following fission reaction is a typical of those occuring in a nuclear electric generating station.
(1_0n) + (235_92U) → (141_56Ba) + (92_36Kr) + 3(1_0n)
(a) find the energy in the reaction. The mass of neutron = 1.008665u, mass of Ba-141 = 140.914411u, mass of Kr-92 = 91.926156u and mass of U-235 = 235.043930u

Answer 1

Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei.
