Chemical Formulas The chemical formula of a molecule or compound states how many atoms of each element are in one of its molecules. This formula is similar to an algebraic formula in its use of symbols. The description of a compound with numbers and symbols is called a chemical formula. chemical formula is writing the elements of a compound, using their abbreviations. Number of atoms in a molecule If there is more than one atom of a type in the molecule, the formula shows it by a small number after the symbol.
