Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Examples of nuclear fission in the following topics: Nuclear Fission. Fission may be spontaneous, but is usually caused by the nucleus of an atom becoming unstable (or "heavy") after capturing or absorbing a neutron. Meaning of nuclear fission. Most of Definition of Nuclear Fission just from $13,9 / page. A model of a fission reaction of uranium-235. Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, often producing free neutrons and lighter nuclei, which may eventually produce photons (in the form of gamma rays). The debate over nuclear power plants has been going on for some time, with nuclear physicists and lawmakers alike throwing around terms like nuclear fission, critical mass, and chain reaction. A nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy. Nuclear fissionis the process of splitting apart nuclei(usually large nuclei). The definition, examples, and differences from nuclear fission will make it easier to understand this concept in detail. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. If a massive nucleus like uranium-235 breaks apart (fissions), then there will be a net yield of energy because the sum of the masses of the fragments will be less than the mass of the uranium nucleus. Since the 1930s, scientists have known that the Sun and other stars generate their energy by nuclear … 'All Intensive Purposes' or 'All Intents and Purposes'? Deuterium and Tritium … (General Physics) the splitting of an atomic nucleus into approximately equal parts, either spontaneously or as a result of the impact of a particle usually with an associated release of energy.

These examples are from the Cambridge English Corpus and from sources on the web. The reason fission occurs is that energy upsets the balance between the electrostatic repulsion between positively-charged protons and the strong nuclear force that holds protons and … Nuclear fission occurs when an atom splits into two or more smaller atoms, most often the as the result of neutron bombardment. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free! The process is accompanied by the release of a large amount of energy. get custom paper. Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). Sometimes shortened to: … Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei. Some fission reactions give off a lot of energy, and are used in nuclear weapons and nuclear reactors.Nuclear fission was discovered in December 1938 by the German nuclear chemist Otto Hahn and his assistant Fritz … In nuclear fission the nucleus of an atom breaks up into two lighter nuclei. Fission definition An atom contains protons and neutrons in its central nucleus. The use of nuclear fusion reactions for electricity generation remains theoretical. “Nuclear fission.” Merriam-Webster.com Dictionary, Merriam-Webster, https://www.merriam-webster.com/dictionary/nuclear%20fission.

Please tell us where you read or heard it (including the quote, if possible). nuclear fission meaning: → fission. Nuclear fission, radioactive decay reaction where heavy nucleus (uranium or plutonium) of atom subdivided or split into two or more smaller, lighter nuclei the splitting of an atomic nucleus into approximately equal parts, either spontaneously or as a result of the impact of a particle usually with an associated … When large nuclei, such as uranium-235, fissions, energy is released. Post the Definition of nuclear fission to Facebook, Share the Definition of nuclear fission on Twitter. The energy released in fusion is related to E = mc 2 (Einstein’s famous energy-mass equation). Nuclear fusion is the reaction in which two or more nuclei combine, forming a new element with a higher atomic number (more protons in the nucleus). On Earth, the most likely fusion reaction is Deuterium–Tritium reaction. Uranium 235 is a fissile isotope and its fission cross-section for thermal neutrons is about 585 barns (for 0.0253 eV neutron).
