Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays, usually by emitting an alpha particle.
It is located in group Actinides, period seven and block f of the periodic table. White radioactive metallic element belonging to the actinoids. Three natural isotopes, U-238, U-235 and U-234. Uranium-235 is used as the fuel for nuclear reactors and weapons. Discovered by Martin H. Klaproth in 1789.
Uranium is a weakly radioactive element discovered in 1789 by Martin Heinrich Klaproth. It is widely used to fuel nuclear power plants and to make high density penetrators. Atomic bomb is also made using Uranium.
History. Uranium was discovered in 1789 by the German chemist Martin Heinrich Klaproth. In 1841, Eugène-Melchior Péligot isolated the first sample of uranium metal by heating uranium tetrachloride with potassium. Antoine Henri Becquerel discovered radioactivity by using uranium in 1896. Electrons per shell. 2, 8, 18, 32, 21, 9, 2.
