Magnesium oxide - Wikipedia

Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H 2 O → Mg(OH) 2), but it can be reversed by heating it ...
