Document Summary

Mineral consistent chemical formula within a short range. Atom smallest unit of an element that possesses the properties of the element. Isotope variety of an element with different numbers of neutrons in the nucleus. Molecule two or more atoms bonded together. Carat = 200 mg of mass (0. 007055 oz. ) Karat = purity of gold = (k). Minerals must be: naturally occurring, inorganic, specific internal structures (crystal lattice), and chemical composition that varies within specific limits, solid. Streak colors left behind on unglazed tiles. Cleavage (fracture if no patterns) how the mineral breaks.
