In Review

A mineral, by definition, is . . .

  1. Inorganic, which means that it is not made by a living organism.
  2. A solid. There is one unusual exception. Native mercury is a mineral and is the only metal that is a liquid at normal temperatures.
  3. Has a regular crystal structure. The crystal structures are described as crystal systems.
  4. Made by nature which means minerals are not made, directly or indirectly, from human activity.
  5. Has a predictable chemical formula.
