(5) Characteristics of Minerals Inorganic- cannot arise from materials that were once part of a living thing Ex.______________ Non-Ex._________________

(5) Characteristics of Minerals Solid- always solid, not a liquid or gas. It has a definite volume and a definite shape Ex._________________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.

Crystalline Structure of a Mineral

Crystal Structure

Crystals 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)
