Quizplus · Accepted Answer

A compound is a substance made up of two or more elements chemically combined in fixed proportions. A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure. All compounds are minerals because they are inorganic solids with a definite chemical composition. However, not all minerals are compounds because some minerals are elements, such as gold and silver.
