235U + 1 neutron 2 neutrons + 92Kr + 142Ba + ENERGY You might have been wondering, "Where does the energy come from?". The mass seems to be the same on both sides of the reaction: 235 + 1 = 2 + 92 + 142 = 236 Thus, it seems that no mass is converted into energy. However, this is not entirely correct. The mass of an atom is more than the sum of the individual masses of its protons and neutrons, which is what those numbers represent. Extra mass is a result of the binding energy that holds the protons and neutrons of the nucleus together. Thus, when the uranium atom is split, some of the energy that held it together is released as radiation in the form of heat. Because energy and mass are one and the same, the energy released is also mass released. Therefore, the total mass does decrease a tiny bit during the reaction
