Uranium | chemical element | Britannica.com Uranium: Uranium (U), radioactive chemical element of the actinoid series of the periodic table, atomic number 92. It is an important nuclear fuel. Uranium constitutes about two parts per million of Earth’s crust. Some important uranium minerals are pitchblende (impure U3O8), uraninite (UO2), carnotite (a

Uranium-238 - Wikipedia Uranium-238 (238 U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction.However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239. 238 U cannot support a chain reaction because inelastic scattering reduces.

Uranium-238 | chemical isotope | Britannica.com In dating: Fission-track dating …during the spontaneous fission of uranium-238. In this unique type of radioactive decay, the nucleus of a single parent uranium atom splits into two fragments of similar mass with such force that a trail of crystal damage is left in the mineral.

Uran – Wikipedia Uran (benannt nach dem Planeten Uranus) ist ein chemisches Element mit dem Elementsymbol U und der Ordnungszahl 92. Im Periodensystem steht es in der Gruppe der Actinoide (7. Periode, f-Block).Uran ist ein Metall, dessen sämtliche Isotope radioaktiv sind. Natürlich in Mineralen auftretendes Uran besteht zu etwa 99,3 % aus dem Isotop 238 U und zu 0,7 % aus 235 U.

Uranium–lead dating - Wikipedia Decay routes. The above uranium to lead decay routes occur via a series of alpha (and beta) decays, in which 238 U with daughter nuclides undergo total eight alpha and six beta decays whereas 235 U with daughters only experience seven alpha and four beta decays.. The existence of two 'parallel' uranium–lead decay routes (238 U to 206 Pb and 235 U to 207 Pb) leads to multiple dating.

Uranium - New World Encyclopedia Uranium is a naturally occurring element that can be found in low levels within all rock, soil, and water. Uranium is also the highest-numbered element to be found naturally in significant quantities on earth and is always found combined with other elements. It, along with all elements with atomic weights higher than iron, are only naturally formed in supernova explosions.

Uranium-235 Half-Life, Fission, Decay, Atomic Mass, Uses Uranium-235 is a naturally occurring isotope of Uranium metal.It is the only fissile Uranium isotope being able to sustain nuclear fission. Uranium-235 is the only fissile radioactive isotope which is a primordial nuclide existing in the nature in its present form since before the creation of Earth.
