WebJun 25, 2024 · A tremendous amount of energy is produced by the fission of heavy elements. For instance, when one mole of U-235 undergoes fission, the products weigh about 0.2 grams less than the reactants; this “lost” mass is converted into a very large amount of energy, about 1.8 × 10 10 kJ per mole of U-235. Nuclear fission reactions … WebAug 24, 2015 · In the case of U 92 235 fissioning to C s 55 137, we know the atomic number of the second fission product is given by: 92 = 55 + Z, i.e. Z = 37, which is the atomic nummber of Rb (rubidium). Now as to the atomic weight of the Rb isotope, also use preservation of neutrons. A U 92 235 nucleus contains 235 − 92 = 143 neutrons and a C …

WebJan 30, 2024 · Asymmetric fission has an average yield 600 times greater than symmetric fission. Number of outer nucleons drastically affects shape of nucleus, which in turn may change the nature of fission symmetry. ... Nuclear fission splits a heavy nucleus such as uranium or plutonium into two lighter nuclei, which are called fission products. Yield refers to the fraction of a fission product produced per fission. Yield can be broken down by: 1. Individual isotope 2. Chemical element spanning several isotopes of different mass number but same atomic number.
