Magnesium oxide. Magnesium oxide (MgO), 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 MgO and consists of a lattice of Mg2+ ions and O2â ions held together by ionic bonding.
Magnesium is more reactive than iron. So Magnesium loses electrons in preference to iron. Magnesium reacts with the oxygen in the air to form Magnesium Oxide, and the iron remains protected, because it has magnesium attached to it. Magnesium is oxidised as it dissolves. Iron ions are reduced to iron atoms. The iron ions take the electrons given out by magnesium, and form iron metal.
