2. Pure Substances Cannot be broken down into simpler substances and still have the same properties.

3. Pure Substances Elements The purest substances known. They contain all the same type of atom.

4. Pure Substances Compounds Combinations of atoms that are “bonded” together. [http://www.cybered.net/library/Teaching_Resources/Chemistry/Naming_ Chemical_Compounds/Image_Gallery/NamingChem-Compounds.jpg]

5. Mixtures Combinations of different types of matter that can easily be separated from one another.

6. Mixtures Homogeneous Mixtures Look the same throughout. Include solutions, colloids, and suspensions. [http://www.guided-wave.com/_img/userfiles/Image/ChemicalFlasks.jpg]

7. Solutions have one substance that is so small it is“dissolved” in another substance

8. Colloids and the Tyndall Effect: Particles are larger in a colloid than in a solution [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG14_21.JPG]

9. A suspension has particles that eventually will settle to the bottom. [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG14_09.JPG]

10. Mixtures Heterogeneous Mixtures These have two or more visible parts. [http://www.chemistry.org/portal/a/c/s/1/resources/ACS/ACSContent/wondernet/images/wn_float_oil.jpg]
