A chemical formula is a concise list of the elements in a compound and the ratios of these elements. Note: By convention, assume that there is only one atom if a subscript is not present. We do not use 1 as a subscript. Ionic compounds exist as alternating positive and negative ions in regular, three-dimensional arrays called crystals.
