In nuclear decay reactions you must be certain that all the combined atomic mass of the reactants equals the combined atomic mass of the products. Although beta decay does not change the mass number of the nucleus, it does result in an increase of +1 in the atomic number because of the addition of a proton in the daughter nucleus. 1. Few radioactive decay examples are discussed in detail in this article. Gamma emission occurs when an excited nucleus (often produced from the radioactive decay of another nucleus) returns to its ground state, which is accompanied by the emission of a high energy photon. These two examples are referred to as induced nuclear reactions. Nuclear fission of U-235 In this reaction, a neutron bombards the nucleus of a uranium-235 nucleus producing krypton-91, barium -142 and 3 more neutrons.
