The simplest are the native elements such as gold (Au) and sulphur (S). Others are more complex such as quartz (SiO2) which has two oxygen (O) atoms for every 1 silicon atom (Si), and calcite (the most common mineral in limestones) whose composition is CaCO3, meaning that for every calcium atom (Ca) there is 1 carbon (C) and 3 oxygen.
