Uranium (pronounced /jʊˈreɪniəm/ yoo-RAY-nee-əm) is a silvery-white metallic chemical element in the actinide series of the periodic table with atomic number 92. It is assigned the chemical symbol U. A uranium atom has 92 protons and 92 electrons. 6 of the latter are val...
Uranium is a naturally occurring radioactive element, which has the atomic number of 92 and corresponds to the chemical symbol U in the periodic table. It belongs to a special group of elements called “actinides” — elements that were discovered relatively late in history. Like all other act...
