Reaction Rates & Equilibrium
12
alpha particle : a positively charged particle, indistinguishable from a helium atom nucleus and consisting of two protons and two neutrons (2 words with space)
beta particle : a high-speed electron or positron, especially one emitted in radioactive decay (2 words with space)
gamma ray : electromagnetic radiation emitted by radioactive decay and having energies in a range from ten thousand (104) to ten million (107) electron volts (2 words with space)
fission : a nuclear reaction in which an atomic nucleus, especially a heavy nucleus such as an isotope of uranium, splits into fragments, usually two fragments of comparable mass, releasing from 100 million to several hundred million electron volts of energy
fusion : a nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy
isotope : one of two or more atoms having the same atomic number but different mass numbers, due to a different number of neutrons in the nucleus
nuclear reactor : any of several devices in which a chain reaction is initiated and controlled, with the resulting heat typically used for power generation and the neutrons and fission products used for military, experimental, and medical purposes (2 words with space)
radioactivity : spontaneous emission of radiation, either directly from unstable atomic nuclei or as a consequence of a nuclear reaction.
artificial transmutation : an artificially induced nuclear reaction caused by the bombardment of a nucleus with subatomic particles or small nuclei (2 words with space)
bombardment : the act (or an instance) of subjecting a body or substance to the impact of high-energy particles
nucleon : a proton or a neutron, especially as part of an atomic nucleus
halflife : the time required for half the nuclei in a sample of a specific isotopic species to undergo radioactive decay
particle accelerator : a device, such as a cyclotron or linear accelerator, that accelerates charged subatomic particles or nuclei to high energies (2 words with space)
