Uranium is a silvery-white metallic element. It is ductile and slightly softer than steel. It has high density, about 70% more than lead, but slightly less than gold. It is radioactive, and slowly decays by alpha decay, though it occasionally spontaneously fissions under the influence of neutrons. In the presence of air, it quickly corrodes and develops a black oxide coating. In nature, it is always found in conjunction with other elements. One of the isotopes, Uranium-235, under the right conditions, can setup a nuclear chain reaction where neutrons split the Uranium-235, producing other nuclides along with more neutrons along with a large amount of energy. This can be controlled, such as in a power plant, or it can be uncontrolled, such as in a weapon.

uranium is a radioactive source of energy.
Uranium is a very heavy metal which can be used as an abundant source of concentrated energy. It is common in the Earth's crust and is found in economic concentrations in a wide variety of geological settings. It is white-ish silvery in colour.
It was discovered in 1789 by Martin Klaproth, a German chemist, in the mineral called pitchblende. It was named after the planet Uranus, which had been discovered eight years earlier.

∙ 8y agoUranium is a silvery grey radioactive metal that on exposure to air rapidly turns dark black. Uranium decays by alpha emission to thorium. Uranium has a very complicated response to neutron radiation depending both on the isotope and the energy of the neutrons (e.g. uranium-235 fissions at all energies, uranium-238 captures low energy neutrons and decays by beta emission to neptunium then plutonium, uranium-238 fissions at very high neutron energies). Only about 0.7% of natural uranium is uranium-235. All uranium was formed in supernova explosions more than 6 billion years ago,

How many electrons and protons does uranium contain?
92 protonsAll the isotopes of uranium has 92 protons.
Does CANDU reactor use enriched uranium?
CANDU Reactors are specifically designed such that they do not require enriched uranium, and can operate entirely on naturally-occurring uranium. A CANDU design is generally used by parties that do not desire uranium enrichment facilities, due to the cost of those facilities. That said, a CANDU reactor CAN use enriched uranium, they are fully capable of supporting that fuel type.
What is the problem with using uranium as energy?
Uranium is toxic and radioactive; leakages of uranium from mines and plants are dangerous.
What does Half-Life of Uranium 235 mean?
Uranium is a radioactive element and conteneously disintegrate into smaller element, that time in which 1g of uranium becomes half g is known as half life period of uranium.
Who in lead with uranium?
Isotopes of lead are the final products of the decay chain of uranium.
Description of the dropping of both bombs?
One was an uranium fission bomb and the other was a plutonium implsion type bomb.
What has the author D G Jacobs written?
D. G Jacobs has written: 'A description of radiological problems at inactive uranium mill sites and formerly utilized MED/AEC sites' -- subject(s): Environmental aspects, Environmental aspects of Uranium industry, Mills and mill-work, Radioactive pollution, Uranium industry

What are 2 molecules that contain uranium?
Examples:Oxides: uranium dioxide, uranium trioxide, uranium octaoxideSalts: ammonium diuranate, uranyl nitrate, uranyl acetate, uranium hehxafluoride, uranium chlorideand many others because uranium is a reactive metal.

What are common combinatons with uranium with other elements?
uranyl nitrate, uranium dioxide, uranium octaoxide, uranium hexafluoride, uranyl acetate, uranium tetrachloride, uranium carbide, uranium nitride, uranium tetraiodide, uranium sulfide, ammonium diuranate, etc.
Is uranium in a compound?
Some examples of uranium compounds are: uranyl nitrate, uranium dioxide, uranium hexafluoride, uranium tetrachloride, triuraniumoctaoxide, uranyl acetate, uranium iodide, uranium nitride, uranium, sulfide, uranium carbide, uranyl sulfate, etc.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What are uraniums common compounds?
uranyl nitrate, uranium chloride, uranium tetrafluoride, uranium hexafluoride, uranium dioxide, uranium octaoxide, uranyl acetate, uranyl sulfate, uranyl oxalate, uranium carbide, uranium nitride, uranium sulfide, uranium sulfate, uranium selenide, etc.
What are the masses of uranium and in uranium oxide?
The percentage of uranium in uranium dioxide is 88,149.
Are there different types of uranium?
Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.
Is uranium magnetic?
Uranium is a paramagnetic element.
