Key Concept #1What is a mineral?It is a
substance which has a
naturally occurring inorganic
definite chemical composition
What would be the opposite of this?
man-made organic random composition

Key Concept #2What causes minerals to have different physical properties?
their internal arrangement of atoms
Key Concept #2Give an example of two minerals which have the same chemical composition but different physical properties Click Here

Key Concept #3The Main Physical Properties
Used to Identify Minerals
Color
a poor indicator
minerals can be multiple colors
many minerals are the same color
Key Concept #3The Main Physical Properties
Used to Identify Minerals
Streak
the powder form of a mineralmore reliable than color
Key Concept #3The Main Physical Properties
Used to Identify MineralsLuster
how light reflects off a mineral
metallic non-metallic
looks like a metal
looks earthy, waxy, greasy or brilliant
Key Concept #3
Cleavage
The Main Physical Properties Used to Identify Minerals
the mineral breaks in a predictable patternbecause of its arrangement of atoms
Key Concept #3
Fracture
The Main Physical Properties Used to Identify Minerals
the mineral breaks randomly
Key Concept #3
Hardness
The Main Physical Properties Used to Identify Minerals
resistance to being scratched
It is NOT the same as breaking!
For example: You can break glass easily with steel.However, steel will not scratch glass.

Key Concept #4Minerals have a definite chemical composition.
What two elements, by mass, make up the greatestpercentage of the Earth’s crust?
siliconoxygen
Key Concept #4Minerals have a definite chemical composition.
These two elements combine to form compounds called
silicates (SiO4)
Key Concept #4Minerals have a definite chemical composition.
They combine in a specific structure called a:
silicon-oxygen tetrahedra
