Minerals – Can you SNIFC it? Definition: a naturally occuring, inorganic solid, with a crystalline structure and definite chemical composition Mineral must be: Solid Naturally occuring Inorganic Formula or Definite chemical composition Crystalline structure

Solid Cannot be deformed (change shape) or change volume ???

Naturally Occurring Cannot be manmade

Inorganic INORGANIC: ORGANIC: Consist of non-living material Consist of living or once living material Coal—made by carbon atoms from ancient trees—trees are living—not a mineral--organic Gold—made by gold atoms—mineral--inorganic

Organic? OR inorganic? ORGANIC VEGTABLES

Formula or Definite chemical composition Any given mineral always has the same chemical composition. We say it has a specific formula. Chemical formulas are a way to describe the specific types and amounts of atoms in a substance. Example: Mineral gold: chemical composition Au (gold) Mineral Diamond: chemical composition C (carbon) Mineral halite: chemical composition NaCl (sodium and chlorine) Mineral quartz: chemical composition SiO2 (one Silicon and 2 Oxygen)

Crystalline structure Unique arrangement of atoms in a crystal
