A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. In empirical formulas, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound, as ratios to the key element.For molecular compounds, these ratio numbers can all be expressed as whole numbers.

Empirical formulas give the relative numbers of the different elements in a sample of a compound, expressed in the smallest possible integers.
