Uranium trioxide (UO 3) is an orange powder and has been used in the manufacture of Fiestaware plates. Other uranium compounds have also been used to make vaseline glass and glazes. The uranium within these items is radioactive and should be treated with care. Uranium's most stable isotope, uranium-238, has a half-life of
Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235. Uranium-235 is the only naturally occurring fissionable fuel (a fuel that can sustain a chain reaction). Uranium fuel used in nuclear reactors is enriched with uranium-235. The chain reaction is carefully controlled using neutron-absorbing materials.
Uranium atoms have 92 electrons and the shell structure is 18.104.22.168.21.9.2. The ground state electronic configuration of neutral uranium is [Rn].5f 3.6d 1.7s 2 and the term symbol of uranium is 5 L 6.. Uranium: description Your user agent does not support the HTML5 Audio element.
To which group does uranium belong? Actinoid (previously called the actinides) group. Read More. share with friends Which the element uranium belong to? Uranium is a member of the actinoids family
Uranium-234, which is a member of the uranium series (the decay chain of uranium-238), decays to lead-206 through a series of relatively short-lived isotopes. Uranium-233 is made from thorium-232 by neutron bombardment, usually in a nuclear reactor, and 233 U is also fissile.

Plutonium was first made in December 1940 at Berkeley, California, by Glenn Seaborg, Arthur Wahl, Joseph Kennedy, and Edwin McMillan. They produced it by bombarding uranium-238 with deuterium nuclei (alpha particles). This first produced neptunium-238 with a half-life of two days, and this decayed by beta emission to form element 94 (plutonium).

Plutonium's most stable isotope, plutonium-244, has a half-life of about 82,000,000 years. It decays into uranium-240 through alpha decay. Plutonium-244 will also decay through spontaneous fission. Only two of plutonium's isotopes, plutonium-238 and plutonium-239, have found uses outside of basic research.
