body-centered cubic (bcc) ( cI2) Barium is a chemical element; it has symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element.
Jun 14, 2024 · barium (Ba), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table. The element is used in metallurgy, and its compounds are used in pyrotechnics, petroleum production, and radiology.

A suspension of barium sulfate is sometimes given to patients suffering from digestive disorders. This is a ‘barium meal’ or ‘barium enema’. Barium is a heavy element and scatters X-rays, so as it passes through the body the stomach and intestines can be distinguished on an X-ray.
Origin of its Name: Its name is derived from the Greek word ‘barys’ which means heavy. Who Discovered the Element: Humphry Davy. When, Where, and How was Barium Discovered. In the early 1600s, a shoemaker called Vincenzo Casciarolo discovered some pebbles near the mountains of Bologna, Italy.
Barium is a chemical element with symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element.
Barium is found as barium sulfate (barite) and barium carbonate (witherite) in the ground. Both of these minerals do not dissolve in water. Barium sulfate hardly dissolves in anything.
Sep 9, 2014 · John Emsley looks at an element that, despite first appearances, has some interesting applications. First isolated in 1808 by Humphry Davy, barium is a toxic metal with a few surprising uses, including preserving works of art.
Barium is the 56th element in the periodic table and has a symbol of Ba and atomic number of 56. It has an atomic weight of 137.327 and a mass number of 138. Barium has fifty-six protons and eighty-two neutrons in its nucleus, and fifty-six electrons in six shells.
Barium is never found free in nature since it reacts with oxygen in the air, forming barium oxide (BaO), and with water, forming barium hydroxide (Ba(OH) 2) and hydrogen gas (H 2). Barium is most commonly found as the mineral barite (BaSO 4 ) and witherite (BaCO 3 ) and is primarily produced through the electrolysis of barium chloride (BaCl 2 ).
