Uranium-235
Uranium-235
Uranium-235 (pronounced: yoo-RAY-nee-uhm two-thirty-five) is an isotope of uranium that is used as a fuel in nuclear reactors and in the production of nuclear weapons.
Etymology
The term "Uranium-235" is derived from the element uranium, named after the planet Uranus, and the atomic mass number 235.
Description
Uranium-235 is a radioactive isotope of uranium. It is one of the few materials that can undergo induced nuclear fission. When a neutron strikes the nucleus of a uranium-235 atom, the nucleus splits, releasing a large amount of energy as well as more neutrons. These neutrons can then cause other uranium-235 atoms to split, creating a chain reaction.
Uses
Uranium-235 is used as a fuel in nuclear reactors due to its ability to undergo induced fission. It is also used in the production of nuclear weapons.
