*just like ‘calcium’*

*MgO*

*AKA “MAGNESIA”*
.
-‘white hygro-scopic solid mineral’ that occurs naturally as ‘periclase’ + 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 (MgO + H2O → Mg(OH)2), but it can be reversed by heating it to separate moisture)
(“magnesium oxide” was historically known as magnesia alba (literally, the white mineral from magnesia – other sources give magnesia alba as MgCO3), to differentiate it from magnesia negra, a black mineral containing what is now known as ‘manganese’)
(while “magnesium oxide” normally refers to MgO, magnesium peroxide MgO2 is also known as a compound)
(according to evolutionary crystal structure prediction, MgO2 is thermodynamically stable at pressures above 116 GPa (gigapascals), and a totally new semiconducting suboxide Mg3O2 is thermodynamically stable above 500 GPa)
.
(because of its stability, MgO is used as a model system for investigating vibrational properties of ‘crystals’)
