But what is a mineral?
______________Occurring
_______________Substance
Orderly Crystalline _______________
Definite Chemical _________________
Generally considered _______________
Talk about each of them and give examples

3. MINERALS – Is it a mineral?
Why would ice be considered a mineral, but water would not?
Is coal considered a mineral? Explain.
When you “grow a crystal” from a kit, are you creating a mineral? Explain.
Name a mineral that you know of – use the definition of a mineral to write a sentence verifying it is a mineral.

4. Mineral Formation Minerals are formed in a few ways:
________________from magma
________________
_____________________________(within the earth)
Hydrothermal Solutions
Minerals formed by the
crystallization of magma

5. Mineral Formation
For each of these ways a mineral is formed, the bottom line is that elements are ____________.
Today we are going to talk about the how they are _________according to which elements are bonded together.

6. Mineral Formation Mineral Groups
Minerals can be classified based on their composition.
We will discuss 6 mineral groups today and how you can know which groups minerals belong to based on their chemical composition.

7. 2.2 Minerals
1. Silicates
_______and _______combine to form a structure called the silicon-oxygen tetrahedron. This silicon-oxygen tetrahedron provides the framework of every silicate mineral.

8. 2.2 Minerals
1. Silicates
Use the periodic table to find the symbol for Silicon.
Use the table to find the symbol for oxygen.
Whenever you see these symbols together in a compound it will be classified as a silicate.
Example: Orthoclase Feldspar - KAlSi 3O 8
What other elements do you see in this compound?
Other examples: Quartz – ________

9. SiO2 - Quartz – used to make glass and gemstones.
It is one of the most abundant minerals found on earth!

10. KAlSi 3O 8 - Feldspar – makes porcelain and china

11. 2.2 Minerals Mineral Groups 2. Carbonates
Minerals that contain the elements ________, _______, and one or more other _______elements
Aragonite – a collectors item

12. 2.2 Minerals Mineral Groups 3. Oxides
Minerals that contain __________and one or more other elements, which are usually metals

13. Oxides
Ice and snow
Zincite – used in semiconductors

14. 2.2 Minerals Mineral Groups 4. Sulfates and Sulfides 5. Halides
Minerals that contain the element _________
5. Halides
Minerals that contain a ________ion plus one or more other elements
6. Native elements
Minerals that exist in __________________
Name 3 examples of Native Elements:

15. Pyrite – “fool’s gold” – mined for iron
Sulfides
Galena – mined for lead
Pyrite – “fool’s gold” – mined for iron

16. Applying Mineral Groups

Barite (BaSO4)
Answer individually, after 5 minutes you will compare with a partner.
Answers: 1 – sulfide, 2 – oxide, 3 – carbonate, 4 – sulfate
