Uranium is a chemically reactive metal belonging to the actinide series. Becquerel discovered radioactivity in uranium in 1896, and its capacity to undergo fission led to its use as a source of energy, though the fissile isotope, uranium-235, has to be separated from the more common uranium-238 before it can be used in nuclear weapons. The atom bomb exploded over Hiroshima in 1945 contained uranium-235
A rare radioactive metal, uranium is found in the mineral pitchblende. The German chemist Martin Klaproth isolated the metal and called it uranium after the planet Uranus, which the astronomer Sir William Herschel had discovered less than a decade before, in 1781.
