| Chemical formula | the kind and number of atoms in a representative unit of a substance |
| Law of definite proportions | in a given compound, elements are combined in proportions by mass and thus by atoms that do not vary; also called Proust’s Law |
| Law of multiple proportions | when different compounds are formed by a combination of the same two elements, different masses of one element combine with the same fixed mass of the other element in a ratio of small whole numbers; also called Dalton’s law |
| Structural formulas | Chemical formulas which show the number, types and arrangement of the atoms |
| Molecular formulas | Chemical formulas that show the actual numbers and types of element in a molecule |
| Empirical formulas | Chemical formulas which only give the smallest whole number ratios of atoms in a chemical formula |
