WebFission decay chains and charge distribution. In order to maintain stability, the neutron-to-proton ( n / p) ratio in nuclei must increase with increasing proton number. The ratio remains at unity up to the element calcium, with 20 protons. It then gradually increases until it reaches a value of about 1.5 for the heaviest elements. Nuclear fission can occur without neutron bombardment as a type of radioactive decay. This type of fission (called spontaneous fission) is rare except in a few heavy isotopes. In engineered nuclear devices, essentially all nuclear fission occurs as a "nuclear reaction" — a bombardment-driven process that results from the collis…

WebJan 30, 2024 · Chain Reaction. Chain Reactions are basically fission reactions which through the products produce more chain reactions. One of the most well-known and useful examples of a chain reaction is of U 235 which is used to harness nuclear energy. For U 235 on average 2.5 neutrons are emitted, starting on average two more fission reactions. … great one fallow cotw
