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 oxide, MgO. Higher melting point than sodium chloride: around 2,800ÂºC. This is because its Mg 2+ and O 2- ions have a greater number of charges, so they form stronger ionic bonds than the Na + and Cl-ions in sodium chloride.Because magnesium oxide stays solid at such high temperatures, it remains non-conductive.It is used for high-temperature electrical insulation.Page: 1  1. 2  2. 3  3.his is because its Mg 2+ and O 2- ions have a greater number of charges, so they form stronger ionic bonds than the Na + and Cl-ions in sodium chloride.
