Uranium

Uranium is atom number 92 — every Uranium atom has exactly 92 protons in its center, and that number is what makes it Uranium and nothing else. Its symbol is U. At room temperature it is a solid.

Uranium is a chemical element with symbol U and atomic number 92. It is a silvery-white metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.

Summary from the source dataset, derived from Wikipedia (CC BY-SA 3.0) · original article

Uranium sits in period 7, group 3 of the f-block. Its 92 electrons fill shells of 2, 8, 18, 32, 21, 9, 2 — written as [Rn] 5f3 6d1 7s2. Its electronegativity is 1.38 on the Pauling scale, and pulling the first electron off takes 597.6 kJ/mol. The outermost shell holds 2 electrons — the ones that do all the chemistry.
