Many compounds exhibit polymorphism. It has been claimed that "every compound has different polymorphic forms, and that, in general, the number of forms known for a given compound is proportional to the time and money spent in research on that compound." The phenomenon was discovered in 1832 by Friedrich Wöhler and Justus von … WebA polymorph is a mineral with the same chemical composition but a different internal structure. Aragonite and calcite are polymorphs – both contain calcium carbonate (CaCO3) but have different internal structures.
