Magnesium oxide - Wikipedia

Magnesium, oxide, or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of ,magnesium,. It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic bonding. ,Magnesium, hydroxide forms in the presence of water, but it ,can, be reversed by heating it to ,remove, moisture. ,Magnesium, oxide was historically known as …
