Nuclear reaction | Definition, History, Types, & Facts | Britannica
网页nuclear reaction, change in the identity or characteristics of an atomic nucleus, induced by bombarding it with an energetic particle. The bombarding particle may be an alpha particle, a gamma-ray photon, a neutron, a proton, or a heavy ion.
Nuclear reaction - Wikipedia
网页In nuclear physics and nuclear chemistry, a nuclear reaction is a process in which two nuclei, or a nucleus and an external subatomic particle, collide to produce one or more new nuclides. Thus, a nuclear reaction must cause a transformation of at …
Nuclear Reactions | Definition, Types & Quiz | nuclear-power.com
网页A nuclear reaction is a process when two atomic nuclei or subatomic particles interact to produce one or more new particles or gamma rays. Thus, a nuclear reaction must cause a transformation of at least one nuclide to another.
NUCLEAR 101: How Does a Nuclear Reactor Work?
网页2023年8月2日 · Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.
24.3: Nuclear Reactions - Chemistry LibreTexts
网页The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of …
What is Nuclear Energy? The Science of Nuclear Power
网页2022年11月15日 · Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – …
8.1: Introduction to nuclear chemistry - Chemistry LibreTexts
网页Nuclear reaction. Nuclear reactions involve changes in the nucleus of an atom. A nuclear reaction may result in one or more of the following: i) conversion of an atom to its isotope or an atom of another element, ii) conversion of mass into energy or vice versa, and iii) release of nuclear radiations.

Science 101: Nuclear Energy - Argonne National Laboratory
网页Nuclear reactors split atoms of uranium, a mildly radioactive element, to form heat. This process releases heat and neutrons. Some of these neutrons go on to collide with other uranium atoms, causing them to fission, which keeps the nuclear reaction going.
