WebNuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process. Nuclear fission occurs with heavier elements, where the electromagnetic force pushing the nucleus apart ... WebHomolytic fission, or hemolysis, is a kind of bond fission that separates a particular molecule. An electron is retained in each of the molecule’s original fragments. As a …
WebJun 5, 2014 · The fission process becomes self-sustaining as neutrons produced by the splitting of atom strike nearby nuclei and produce more fission. This is known as a chain reaction and is what causes an atomic explosion. When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some … WebHomolytic fission (sometimes referred to as hemolysis) is a type of bond fission that involves the dissociation of a given molecule wherein one electron is retained by each of the original fragments of the molecule.
