How are minerals classified based on anion groups? Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition.

Are minerals classified by anions? Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral.
Why are minerals grouped by anion? Minerals are organized according to the anion or anion group (a group of atoms with a net negative charge, e.g., SO42–) they contain, because the anion or anion group has the biggest effect on the properties of the mineral.
