Barium Oxide is a unique chemical compound that attracts water molecules from the surrounding environment at room temperature. This is widely used in coating for hot cathodes in cathode ray tubes, production of optical crown glass and many more. It is also used as a drying agent for gasoline and solvents. This chemical appears from white colour to yellow colour.

Barium Oxide Structural Formula
The structural depiction of Barium Oxide is as shown in the figure below. One ion of barium neutralizes one ion of oxygen, hence those two ions combine to form barium oxide, BaO.
Barium on getting oxidized forms the ionic compound is BaO, represented as below
Ba2++O2−→BaO
