Nuclear Chemistry
Nuclear Chemistry Review
| Question | Answer |
|---|---|
| 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. |
| gamma ray | electromagnetic radiation emitted by radioactive decay and having energies in a range from ten thousand to ten million electron volts |
| particle accelerator | a device, such as a cyclotron or linear accelerator, that accelerates charged subatomic particles or nuclei to high energies |
| radioactivity | spontaneous emission of radiation, either directly from unstable atomic nuclei or as a consequence of a nuclear reaction |
| nucleon | a proton or a neutron, especially as part of an atomic nucleus |
| bombardment | act (or an instance) of subjecting a body or substance to the impact of high-energy particles |
| alpha particle | positively charged particle, indistinguishable from a helium atom nucleus and consisting of two protons and two neutrons |
| half-life | the time required for half the nuclei in a sample of a specific isotopic species to undergo decay |
| 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 |
| 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 |
| beta particle | a high-speed electron or positron, especially one emitted in radioactive decay |
| fusion | a nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy |
