An induced nuclear fission event. A thermal (slow-moving) neutron is absorbed by the nucleus of a uranium-235 atom, which in turn splits into fast-moving lighter elements (fission products) and free neutrons. The particular elements and number of neutro |

 Nuclear fission is a process in which a heavy nucleus—usually one with a nucleon number of two hundred or more—separates into two nuclei. Usually the division liberates neutrons and electromagnetic radiation and releases a substantial... summary from source:

Nuclear fission is a process in which the nucleus of an atom splits, usually into two daughter nuclei. Spontaneous fission of uranium and other elements in Earth's interior provides an internal source of heat that drives plate tectonics. Fission... summary from source:

Nuclear fission is a process in which the nucleus of an atom splits, usually into two pieces. This reaction was discovered when a target of uranium was bombarded by neutrons. Fission fragments were shown to fly apart with a large release of energy. The... summary from source:

 The first splitting of an atom by John Douglas Cockroft and Ernest Thomas Sinton Walton in 1932 was a momentous occasion in physics. The two researchers found that the two helium atoms produced when a proton collides with a lithium nucleus have more... summary from source:
 Nuclear Fission Summary

When a neutron strikes the nucleus of certain isotopes, the nucleus breaks apart into two roughly equal parts in a process known as nuclear fission. The two parts into which the nucleus splits are called fission products. In addition to fission... summary from source:
 Nuclear Fission Summary
143 words, approx. 1 pages
Division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles. The energy released in the fission of one uranium nucleus is about 50... summary from source:

The splitting of the nucleus of an atom with accompanying release of energy. It is the principle under which NUCLEAR REACTORS generate power. See also: NUCLEAR FUSION;... summary from source:
 Nuclear fission Summary
5,208 words, approx. 17 pages
Nuclear fission is the splitting of the nucleus of an atom into parts (lighter nuclei) often producing photons (in the form of gamma rays), free neutrons and other subatomic particles as by-products. Fission of heavy elements is an exothermic reaction...
