WebThe mass of an element's nucleus as a whole is less than the total mass of its individual protons and neutrons. To calculate the energy released during mass destruction in both nuclear fission and fusion, we use Einstein’s equation that equates energy and mass: (7.5.1) E = m c 2. with m is mass (kilograms), c is speed of light (meters/sec ... WebDescription of fission 1. A heavy nucleus, such as U-235, captures a slow neutron, splits into lighter nuclei (fission fragments), releases energy and excess neutrons 2. The fission …
