The name of the ionic compound MgO is magnesium oxide. This compound is formed when magnesium (Mg) reacts with oxygen (O). In this reaction, magnesium loses two electrons to form a Mg2+ ion, while oxygen gains two electrons to form an O2- ion. The electrostatic attraction between these oppositely charged ions results in the formation of magnesium oxide.
Magnesium oxide is a white, solid substance that is commonly used in various applications, including as a refractory material in furnaces, as an ingredient in cement, and as a dietary supplement to provide magnesium to the body.
