1. Classifying Matter
Elements , Compounds and Mixtures

2. Element : simplest form of matter that has a unique set of properties
Examples:
Oxygen
Hydrogen
Carbon

3. Periodic Table of Elements

4. Compound : substance that contains 2 or more elements chemically combined in a fixed proportion.
Examples:
Water, H2O
Sucrose, C12H22O11
Carbon Dioxide, CO2

5. Mixture: a physical blend of two or more substances that are not chemically combined

6. Describing Matter Heterogeneous Mixture Homogeneous Mixture
Composition is NOT uniform throughout
Examples:
Salad
Chocolate Chip Cookie
Chicken Noodle Soup
Composition is uniform throughout
Also called a solution.
Examples:
Air
Steel
Vinegar
Salt
Water
Milk

10. Heterogeneous mixture
Physical combination of
two or more substance
Heterogeneous mixture
Physical combination
Of 2 or more substances
that is different throughout.
Homogenous mixture
Physical combination

11. Separating Mixtures
Differences in physical properties can be used to separate mixtures.
Examples:
Filtration
Distillation
Magnetism

12. Filtration Separates solids from a liquid in a heterogeneous mixture.

13. Distillation Process which separates mixtures of liquids with different boiling points.
