1. WARM UP “Your future occupation depends on your present education.”
1. Where are you going to college?
2. What are some careers you think you might like to have?
3. Do the schools you want to go to allow you to prepare for the careers you listed?

2. Matter and Atomic Theory
Chem II

3. Types of Matter Elements Characteristics Atomic Theory (John Dalton):
Pure substance
Definite properties and proportions
Cannot be broken down
Atomic Theory (John Dalton):
#1: Made of atoms (Democritus)
#2: Made entirely of a certain, unique atom

4. Types of Matter Compounds Characteristics Atomic Theory:
Pure substance
Can be broken down
Atomic Theory:
#3: Made of atoms of more than one element
#4: Can be broken down into elements or changed, but the atoms can’t be destroyed

5. Types of Matter Mixtures Properties and proportions can vary
Homogeneous or heterogeneous
Separated by physical properties

6. Physical Properties Mass, density
Melting / boiling point (state of matter)
Solids: fixed atoms
Liquids: flowing atoms
Gases: freely moving atoms

7. Chemical Properties
Describe reactions
Rust
Flammability, reactivity

8. WRAP UP
Compare and contrast elements, compounds, and mixtures – use a Venn diagram.

9. WARM UP List 2 examples of elements. List 3 examples of compounds.
List 4 examples of mixtures.

10. WRAP UP
Compare and contrast physical and chemical properties – use a Venn diagram.
