barium (Ba),chemical element, one of thealkaline-earth metalsof Group 2 (IIa) of theperiodic table. The element is used inmetallurgy, and itscompoundsare used in pyrotechnics,petroleum production, andradiology. Element Properties atomic number56 ...
Barium on the periodic table can be found in period 6 of group 2. Group 2 (IIa) of the periodic table is also called the alkaline-earth metals group. Barium is the fifth element in group 2- the alkaline-earth metals group- of the periodic table. Other elements found in this group inc...
The mixture is heated in a vacuum (133 millinewtons per sq m, 10-3mm Hg) at 1100°-1200° C. The barium evaporates and is deposited on the cold portions of the apparatus. The process is conducted in periodic-action electrovacuum equipment, which permits successive reduction, distillation, ...

A dense, low-melting reactive metal; the fifth member of group 2 (formerly IIA) of the periodic table and a typical alkaline-earth element. The electronic configuration is that of xenon with two additional outer 6s electrons. Barium is of low abundance; it is found as witherite (BaCO3) and...
As an alkaline earth element (Group IIA of the periodic table), barium shares many physical and chemical properties with the other alkaline earths, which include beryllium, magnesium, calcium, strontium, and radium. Barium readily loses its outer two electrons, forming a divalent cation (Ba +2 ...
