Lets look further… into how the crystalline structure is formed!

Elements – a substance in its purest state, unable to be broken down further

Atoms-smallest part of the element and has all properties making the element.

Compound-substance made of two or more elements, chemically joined.

The compound containing sodium (Na) and chloride (Cl) make up….

Crystals also make up minerals!

Crystals -solid, geometric forms of minerals produced by a repeating pattern of atoms, present throughout the space of the mineral.

• Each mineral is made up of its own crystalline structure

Types of Minerals

Silicate minerals• Contain silicon and oxygen• Make up more than 90% of earths crust

Examples• Quartz Feldspar Biotite mica

Types of Minerals

Nonsilicate minerals• Does not contain combo of silicon and oxygen
