Living. Minerals are INORGANIC.

Particles lined up in a repeating

pattern form what?

Crystal Structure.

To be classified as a mineral, something must

meet 5 requirements. What are they?

1. Naturally occurring2. Inorganic3. Solid4. Crystal structure5. Chemical

composition

Explain why Coal could be a mineral ANDAND why it is not.

Coal is NOT a mineral.It is a naturally occurring

solid, but comes from plant matter, so it is ORGANIC.

Name 2 2 major ways minerals

form.

1. By cooling of molten material.2. Dissolved in water.3. Evaporation.

What common mineral is found in

dried lakes?What is its chemical

formula?

Salt.Its chemical formula is Sodium Chloride -

NaCl

Molten material is known by two names.

What are they and why?

Magma & Lava.Magma is under

ground, Lava is above.

Under what conditions do large

crystals form?

Small crystals?

High temperature, slow cooling.

Low temperature, fast cooling.

What is a vein?

How does it form?

•Channel of minerals that is different from the surrounding rock.•When solution crystallizes bellow the surface.

There are 7 primary ways to identify a

mineral. List 4 of them.

1. Color2. Streak3. Luster4. Hardness5. Cleavage/Fracture6. Crystal Structure7. Density

The scale the rates the hardness of minerals

is called what?

The Mohs hardness scale.

Give three special properties a mineral

might have.

1. Fluorescence2. Magnetic3. Reacts to acid4. Generates electricity5. Radioactive

What is the softest mineral on the Mohs

hardness scale?The hardest?

Talc = 1Diamond = 10

Describe the differences between fracture & cleavage.

Fracture is when something breaks

irregularly.Cleavage breaks

along flat surfaces.

Minerals valued primarily for their

beauty are called what?

Gemstones.

A mineral deposit that contains a metal or is

economically useful is called what?

The gold rush of 1849 brought thousands to the

West. What is this search for minerals called?

Prospecting.

Iron is an element. Why is steel different

and what is this called?

Steel is an alloy – a solid mixture of two or

more metals.

What is an atom?

List the 3 subatomic particles.

An atom is the smallest unit of an element.

The subatomic particles are Protons, Electrons, &

Neutrons.

What is an element?

Substance composed of a single kind of atom.

What are the differences between a compound and

a mixture?

Compounds are chemically combined

whereas mixtures are not.

Define DENSITYDENSITY.What is the formula for density and its units?

Amount of matter in a given space.

D = mass divided by volume

Units are g/mL

How many neutrons does Potassium have?

Neutrons = Atomic Mass – Atomic #39 – 19 = 20 Neutrons
