What are the three layers of the planet?
Atmosphere, Hydrosphere, Lithosphere
What is an ore?
A solid material containing metals or other elements of intrest
To mine - or not to mine depends on what?
- Amount of ore at the site
- Percent of metal in ore
- Type of mining/processing needed to extract metal
- Distance of mine from refining facility
- Metal's supply vs. demand status
Why are gold, silver, and copper among the first elements discovered even though they are more rare than aluminum, iron and calcium?
They are often found in their elemental state due to their low reactivity, while others are reactive and must be refined from their ores
What are the differences between Au and Li?
Au is does not interact with any other element, while Li interacts with many elements
Where are the most reactive metals found?
Where are the least?
- The most reactive metals are on the left side
- The least reactive are on the right side
What is an oxidation
A chemical change in which a species loses electrons

Ex.
Cu --> Cu++ + 2e- Oxidation

(OIL)
What is a reduction?
A chemical change in which a species gains electrons

Ex.
Cu++ + 2e- --> Cu Reduction

(RIG)
What is the conservation of charge
Whenever one species gains electrons another is losing them.
(This means oxidation and reduction ALWAYS occur in the same reaction)
What does the : in Mg: mean?
: represents 2 easily removed electrons

Ex.
Mg: --> Mg++ + 2e-
What is the answer to this equation?
Ag + e- --> ?
Ag^0
What is the oxidizing agent?
It takes the electrons
What is the reducing agent?
It supplies the electrons
