Uranium (U) - The Chemical Elements A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z). [1] The definitive visualisation of all elements is the periodic table of the elements, whose history along the principles of the periodic law was one of the founding.

uranium (U), radioactive chemical element of the actinoid series of the periodic table, atomic number It is an important nuclear fuel. Uranium constitutes about two parts per million of Earth’s crust. Some important uranium minerals are pitchblende (impure U3O8), uraninite (UO2), carnotite (a potassium uranium vanadate), autunite (a calcium uranium phosphate), and torbernite (a copper.

Uranium (U) Element: History, Properties, Reactions, Uses Uranium is a heavy, lustrous, silvery-white metal, capable of taking a high polish. It exhibits three crystallographic modifications: alpha, beta, and gamma. It is a bit softer than steel; not hard enough to scratch glass. It is malleable, ductile, and slightly paramagnetic. When exposed to air, uranium metal becomes coated with a layer of oxide.
