1. What is Matter?

2. CLASSIFYING MATTER
Matter is a term that describes anything that has mass and volume (takes up space).

3. Solutions Colloids
Suspensions

4. 1. SUBSTANCES
Substances cannot be separated by physical methods. They are either elements or compounds
Examples:
salt
gold

5. 2. MIXTURES
Mixtures contain more than one kind of matter.

6. See the periodic table for a complete list of the elements!
Some substances are elements and contain only one kind of matter (atoms). They cannot be separated by ordinary chemical or physical methods.
Examples:
silver
helium
See the periodic table for a complete list of the elements!

7. COMPOUNDS
Compounds contain two or more kinds of matter (atoms), but cannot be separated without changing the substance.
Examples:
water
sugar

8. HOMOGENEOUS MIXTURE A mixture that is the same throughout. Examples:
coffee
brass
air

9. HETEROGENEOUS MIXTURE
A mixture in which different samples are not necessarily the same.
Examples:
chicken soup
salad dressing

10. All mixtures share one common property:
They can be separated by ordinary physical methods.
Examples: sorting, filtering, solubility, magnetic properties, density, heating, or cooling.

11. Mixtures There are several types of mixtures:
Solution: homogenous mixture that with small unseen particles that do not settle (light passes through)
Colloids: heterogenous mixture that has visible large particles that do not settle out (light scatters and does not pass through)
Suspension: heterogeneous mixture that has liquid and solid particles that settle out

12. So… all mixtures are either homogeneous or heterogeneous and all substances are either elements or compounds.
