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 Mg ions and O 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 remove moist…
WebIn SO₄²⁻, the more electronegative O atoms all get the shared pairs to the S atom. This gives them eight valence electrons each, so their oxidation numbers are each -2. The S atom is left with no valence electrons.
