1. Pure Substances and Mixtures SNC1L

2. Matter can be divided into two categories Pure Substances All the particles are the same.

3. Matter can be divided into two categories Mixtures Pure Substances All the particles are the same. There are different types of particles mixed together.

4. Pure Substances can be divided into two categories Elements The atoms that make up the particles are identical.

5. Pure Substances can be divided into two categories Compounds Elements The atoms that make up the particles are identical. The particles are made of different atoms bonded together.

6. Elements All elements (the different types of atoms) are listed on the Periodic Table.

7. Mixtures can be divided into two categories Heterogeneous The different parts are visible and can be separated mechanically.

8. Mixtures can be divided into two categories Homogenous Heterogeneous The different parts are visible and can be separated mechanically. The different parts are not visible.

9. Suspension A Heterogeneous mixture made of a liquid ans solid particles that settle. Example: River Water P. 466 draw figure 7

10. Colloid A heterogeneous mixture whose components never settle. Example: Milk, smoke, fog Particles are large enough to scatter light (Tyndall Effect)

11. Solution The same thing as a homogeneous mixture A solute is dissolved in a solvent Examples: Kool-aid, coffee, tea, air, gasoline, steel
