Uranium, Plutonium, and Radium Fred A. MettlerJr. MD, MPH, Arthur C. Upton MD, in Medical Effects of Ionizing Radiation (Third Edition), 2008 URANIUM General Uranium is a silvery, heavy metal that is ductile and malleable. Uranium is element number 92 and occurs only in radioactive form....
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 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 by emitting an alpha particle. The...

Of all the elements that make up the Earth’s crust,uraniumis reasonablyabundant, coming in at 49th place, ahead of elements such as tin, tungsten and silver. Ever since humankind began to exploit uranium for its fissile properties in energy production, this abundance has also translated into...
In other words, the crust material per ton contains 2.5g of uranium averagely, which is higher than the content of tungsten, mercury, gold, silver and other elements. The contents of uranium are uneven in various kinds of rocks. For instance, its content in the granite is high, averagely ...
