made• Ex._______________ Non-ex.___________

(5) Characteristics of Minerals• Solid- always solid, not a liquid or gas. It has a

definite volume and a definite shapeEx._________________ Non-ex.____________

(5) Characteristics of Minerals• Crystalline Structure- particles must line up in a

pattern that repeats over and over again

• Ex.______________ Non-ex._____________

Crystals• Crystals are solid, geometric forms produced by a

repeating pattern of atoms or molecules that are present throughout the mineral.

• A crystal’s shape is determined by the arrangement of the atoms or molecules within the crystal.

• All minerals can be grouped into crystal classes according to the kinds of crystals they form.

Crystal StructureCrystals have a definite pattern….. This crystal prism has a pattern or design that it creates as light passes through it.

(5) Characteristics of Minerals• Definite Chemical Composition- always contains

certain elements in definite proportions. NaCl (salt)
