Uranium, U, is a radioactive metallic element, found in the
actinide series of inner transition metals in
Group IIIa of the
- Atomic Number : 92
- Relative Atomic Mass : 238.03
- Uranium in the form of its oxide was discovered by M H Klaproth
- Uranium, U, was isolated as the metal by E M Peligot in 1842AD.
Uranium can be found as
- Pitchblende or Uraninite, U3O8, and
- Carnotite, KUO2(VO4).3H2O.
Uranium is concentrated from pitchblende to yield uranium dioxide and
this dioxide is then converted to uranium tetrafluoride by heating
with hydrofluoric acid, which is then reduced to the metal with Carbon.
- is a hard white solid, but normally exists in the form of a
highly divided black powder,
- is primarily of interest because of its radioactive properties.
Uranium is a reactive metal and it resembles Molybdenum
and Tungsten in chemical properties.
Uranium is attacked slowly by dilute hydrochloric acid.
- Uranium is used as a colourant in pottery and the manufacture of glass.
- Uranium is used in the nuclear industry as a fissionable material.
