Description of uranium

Answer 1

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.

Answer 2

It's an element. # 92 on the list, and radioactive.

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.

Answer 3

Uranium 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,

Answer 4

Uranium is a heavy, naturally radioactive metallic element. It is commonly used as a fuel in nuclear power plants to generate electricity. Uranium has several isotopes, with uranium-235 being the most commonly used in nuclear reactors due to its ability to sustain a nuclear chain reaction.
