A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. In empirical formulae, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound, by ratios to the key element.
The structure of Hydrogen sulfide is similar to that of water. In an H2S molecule, three atoms are present in total. Amongst the three, two are hydrogen and one of sulphur.
