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 MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .
Magnesium oxide and other magnesium compounds are also used in the agricultural, chemical, and construction industries. Magnesium oxide from calcination is used as an electrical insulator in fire-resistant cables. [15] Other applications include: Magnesium hydride is under investigation as a way to store hydrogen.

Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols , normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
The Hill system (or Hill notation) is a system of writing empirical chemical formulae, molecular chemical formulae and components of a condensed formula such that the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms next, and then the number of all other chemical elements subsequently, in alphabetical order ...
Beside the lambda notation, as used in the IUPAC nomenclature of inorganic chemistry, [18] oxidation state is a more clear indication of the electronic state of atoms in a molecule. The oxidation state of an atom in a molecule gives the number of valence electrons it has gained or lost. [19]

The structure of MgO 2 has been calculated as a triangular shape with the O 2 molecule binding side-on to the magnesium. This arrangement is a result of the Mg + donating charge to the oxygen and creating a Mg 2+ O 2 2−. The bond between to O 2 and the magnesium atom has an approximate dissociation energy of 90 kJ mol −1. [1]
