 Barium Iron Oxide

Barium is a Block S, Group 2, Period 6 element with an atomic weight of 137.27. The number of electrons in each of barium’s shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s². Barium is a member of the alkaline-earth metals. The barium atom has a radius of 222 pm and a Van der Waals radius of 268 pm.

Barium was discovered by Carl Wilhelm Scheele in 1772 and first isolated by Humphry Davy in 1808. In its elemental form, barium is a soft, silvery-gray metal. Industrial applications for barium include acting as a “getterer,” or unwanted gas remover, for vacuum tubes, and as an additive to steel and cast iron.

Barium is also alloyed with silicon and aluminum as load-bearing alloys. The main commercial source of barium is the mineral barite (BaSO₄) it does not occur naturally as a free element . The name barium is derived from the Greek word “barys,” meaning heavy.

Iron:

Iron is a Block D, Group 8, Period 4 element with an atomic weight of 55.845. The number of electrons in each of Iron’s shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d⁶ 4s². The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC.

In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth’s crust and the most common element by mass forming the earth as a whole. Iron is rarely found as a free element, since it tends to oxidize easily.

It is usually found in minerals such as magnetite, hematite, goethite, limonite, or siderite. Though pure iron is typically soft, the addition of carbon creates the alloy known as steel, which is significantly stronger.
