where is uranium located on the periodic table?
atomic number 92
uranium is a chemical element with the 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 is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. the most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on earth) and uranium-235 (which has 143 neutrons). uranium has the highest atomic weight of the primordially occurring elements. its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. it occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite.
