The subscripts indicate the amount of each element present in the compounds in a chemical equation. For example, H2O indicates that each molecule of water contains two atoms of hydrogen and one atom of oxygen. The lack of a subscript is understood to mean the number one. For an ionic compound, such as magnesium chloride, MgCl2, the subscripts indicate that each formula unit contains one magnesium ion and two chloride ions.
