WebJun 25, 2024 · Unlike a chemical reaction, a nuclear reaction results in a significant change in mass and an associated change of energy, as described by Einstein’s equation. Nuclear reactions are accompanied by large changes in energy, … While the number of possible nuclear reactions is immense, there are several types that are more common, or otherwise notable. Some examples include: Fusion reactions — two light nuclei join to form a heavier one, with additional particles (usually protons or neutrons) emitted subsequently.Spallation — a … See more 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 … See more In 1919, Ernest Rutherford was able to accomplish transmutation of nitrogen into oxygen at the University of Manchester, using alpha particles … See more Kinetic energy may be released during the course of a reaction (exothermic reaction) or kinetic energy may have to be supplied for the reaction to … See more If the reaction equation is balanced, that does not mean that the reaction really occurs. The rate at which reactions occur depends on the … See more Nuclear reactions may be shown in a form similar to chemical equations, for which invariant mass must balance for each side of the equation, and in which transformations of particles must follow certain conservation laws, such as conservation of … See more In writing down the reaction equation, in a way analogous to a chemical equation, one may, in addition, give the reaction energy on the right side: Target nucleus + … See more In the initial collision which begins the reaction, the particles must approach closely enough so that the short-range strong force can affect them.
