Barium Oxide Formula: Barium oxide formula is BaO. Barium oxide, commonly referred to as baria, is a white, moisture-absorbing, non-combustible compound represented by the chemical formula BaO. It holds a cubic crystalline structure and finds applications in cathode ray tubes, crown glass production, and as a catalyst. It should be noted that barium oxide can be harmful to human skin, and if swallowed of significant amounts can result in irritation. In extreme cases, excessive exposure to barium oxide can be fatal.
Barium oxide is produced by either heating barium carbonate in the presence of coke, carbon black, or tar, or by thermally decomposing barium nitrate.
Barium is an alkali metal with the chemical symbol Ba and an atomic number of 56, placing it as the fifth element within Group 2 of the periodic table. Due to its high reactivity, barium is never found naturally in its pure elemental form. The most common minerals containing barium are barite and witherite.
Barium, denoted by its chemical symbol Ba, holds an atomic mass of 137.327 unified atomic mass units and holds an atomic number of 56, placing it in Group 2 of the periodic table. Its Van der Waals radius measures 268 picometers, while it undergoes a phase transition from solid to liquid at a melting point of 727°C. The density of barium stands at 3.5 grams per cubic centimeter at 20°C. Furthermore, barium exhibits a standard reduction potential of –2.90 volts. It is consistent with its oxidation state of 2+.
Oxygen is a substantial constituent of Earth’s atmosphere and it comprises roughly 21% in the atmosphere, and it is known for its high reactivity. When oxygen reacts with other elements, it forms compounds known as oxides. These oxides are combinations of oxygen with elements that have lower electronegativity. Examples of oxides include Na2O, CaO, Al2O3, CO2, N2O3, Cl2O, and XeO2. Oxides encompass a category of chemical compounds characterized by the presence of one or more oxygen atoms combined with another element, such as Li2O, CO2, H2O, and so forth.
Barium Oxide Formula
Barium Oxide exhibits a cubic crystalline structure. which represents the arrangement of barium oxide (BaO). In this structure, one barium ion takes part in the reaction, and both ions unite to produce barium oxide. This chemical transformation results in the oxidation of barium to create barium oxide. Barium oxide possesses a monoisotopic mass of 153.9 g/mol. Notably, it has one hydrogen bond acceptor and zero hydrogen bond donors, indicating the presence of a single covalently bonded unit.
Barium Oxide Formula Structure
The precise mass and monoisotopic mass of Barium monoxide are both 153.9 g/mol. It has one hydrogen bond acceptor and no hydrogen bond donors. This compound is in its canonical form and consists of a single covalently bonded unit.
