Protons, Electrons and Neutrons make up atoms

Element is a substance composed of a single kind of atom

Minerals are made from one or more elements

Minerals are:

N.O. *Naturally Occurring - not made by man I. *Inorganic - never aliveC. *Crystal - atoms line up to form regular geometric shape with smooth surfacesS. *Solid – not a liquid or a gasS. *Specific composition - recipe does not change (at least not very much)

Identification:

Luster - mineral reflecting light. Metallic or non-metallic.

Color - least useful in identification Streak - powder left on unglazed ceramic tile Hardness - resistance to being scratched. Most

useful to identify. Can use fingernail, penny, or glass. Scale pg 91 developed by Moh.

Identification cont. Density - Mass/Volume Cleavage and Fracture - way it breaks. Also

caused by the internal arrangement of atoms.

conchoidal fracture – breaks like glass

Identification cont. Crystal system - way it grows if it has space.

Caused by internal arrangement of the atoms.
