(Nükleer Bilimler) uranium

(Kimya) The chemical element of atomic number 92, a grey dense radioactive metal used as a fuel in nuclear reactors. (Symbol: U)

A mildly radioactive element with two isotopes which are fissile (U-235 and U-233) and two which are fertile (U-238 and U-234) Uranium is the basic fuel of nuclear energy

the heaviest naturally occurring (metal) element in the earth's crust, exists as three isotopes in the following percentages by weight: U-238, 99 283%; U-234, 0 711%; and U-235, 0 0054%; by radioactivity: U-238, 48%; U-234, 50%; and U-235, 2%; U-235 is the only fissile isotope (capable of sustaining a nuclear chain reaction), i e it is the uranium "bomb material" and nuclear reactor fuel isotope

A chemical element, U, that has an atomic number 92 It reactive with nearly all nonmetals and is used as fuel for nuclear reactors

Hard, grey radioactive metal

and reduced as a heavy, hard, nickel-white metal which is quite permanent

Uranium is a naturally occurring radioactive metal that is used to produce nuclear energy and weapons. a heavy white metal that is radioactive and is used to produce nuclear power and nuclear weapons. It is a chemical element : symbol U (Uranus; because the substance was discovered soon after the planet). Chemical element of the actinide series (with many transition element properties), chemical symbol U, atomic number

A heavy, naturally radioactive, metallic element of atomic number 92 Its two principally occurring isotopes are uranium-235 and uranium-238 Uranium-235 is indispensable to the nuclear industry because it is the only isotope existing in nature to any appreciable extent that is fissionable by thermal neutrons Uranium-238 is also important, because it absorbs neutrons to produce a radioactive isotope that subsequently decays to plutonium-239, an isotope that also is fissionable by thermal neutrons

The heaviest naturally occurring trace element and also a naturally occurring radioactive element which spontaneously "decays" into lighter elements Uranium was originally mined for use as the principal component of atomic bombs Since about 1971, it has been mined exclusively for use as fuel in nuclear power reactors

A naturally radioactive and very dense element Mine Uranium contains 0 7 percent of the isotope Uranium-235, needed for fission Uranium-235 is the principal nuclear fuel material used in today's nuclear power reactors

The basic material for nuclear technology, it is a slightly radioactive, naturally occurring heavy metal that is more dense than lead

A natural and commonly occurring radioactive element which is a mixture of three isotopes; U-234, U-235, and U-238 By weight, natural uranium is about 0 01% U-234, 0 072% U-235, and 99 27% U-238

A heavy silvery-white metallic element, highly radioactive and easily oxidized Of the 14 known isotopes of uranium, 238U is the most abundant in nature

A naturally-occurring element found in some 160 minerals, including phosphate rock

A mildly radioactive element with two isotopes which are fissile (U-235 and U-233) and two which are fertile (U-238 and U-234) Uranium is the basic raw material of nuclear energy

A radioactive element with the atomic number 92 and, as found in natural ores, an average atomic weight of 238 The two principal natural isotopes are uranium-235 (0 7 percent of natural uranium), which is fissionable, and uranium-238 (99 3 percent of natural uranium), which is fertile uranium-233 - A fissionable isotope bred in fertile thorium-232 Like plutonium-239 it is theoretically an excellent material for nuclear weapons, but is not known to have been used for this purpose Can be used as reactor fuel uranium-235 - The only naturally occurring fissionable isotope Natural uranium contains 0 7 percent U-235, light- water reactors use about 3 percent and weapons grade, highly enriched uranium noramlly consists of 93 percent of this isotope uranium-238 - A fertile material Natural uranium is composed of approximately 99 3 percent U-238

A heavy radioactive metal, used chiefly as fuel for nuclear reactors and weapons, but it also has uses in pigments Around 1950, uranium was considered a major factor in United States power and prestige, and did not have nearly the amount of negative connotation it has today

A heavy metal The two principal isotopes of natural uranium are U-235 and U-238 U-235 has the only readily fissionable nucleus which occurs in appreciable quantities in nature, hence its importance as nuclear fuel Only 1 part in 140 of natural uranium is U-235

A silvery, heavy, radioactive, polyvalent metallic element that is found especially in pitchblende and uraninite and exists naturally as a mixture of three isotopes of mass number 234, 235, and 238 in the proportions of 0 006 percent, 0 71 percent, and 99 28 percent, respectively (U, Atomic Number: 92)

{i} silvery white radioactive metallic element whose atomic number is 92 used in nuclear reactions and atomic bombs
