However, there is a class of compounds, called non-stoichiometric compounds, that cannot be represented by small integers. Such a formula might be written using decimal fractions, as in FeO, or it might include a variable part represented by a letter, as in FeO, where x is normally much less than 1. A chemical formula used for a series of compounds that differ from each other by a constant unit is called a "general formula". It generates a homologous series
