8 mar 2022 · A chemical formula indicates the type at ratio of atoms in a compound. Here are examples of different chemical formulas for butane. A chemical formula is notation that shows the number and type of atoms in a molecule. In other words, it is a written representation of a three-dimensional object.
The formula unit is the absolute grouping represented by the empirical formula of a compound, either ionic or covalent. Empirical formulas are particularly useful for describing the composition of ionic compounds, which do not contain readily identifiable molecules.
