Coal is composed of carbon. Is it a mineral?

1 Answer

No, coal is not considered a mineral because it is formed from organic matter.

Explanation:

There are five properties that all minerals have to have to be considered a pure mineral.

  • must be naturally occurring in the environment (Not made in a laboratory)
  • made from inorganic matter (Coal breaks this rule because coal is made from plant matter)
  • have a specific chemical composition
  • have crystalline solids
  • have atoms that are arranged in a repeated pattern

Best of Luck
