1. Chapter 1: Introduction to Chemistry Section 1.2 Chemistry and Matter

2. Matter It’s everywhere! –Desks, skin, clothes, food Can be invisible –Air, CFC, Ozone

3. Chemistry The study of matter and the changes it undergoes

4. Matter and Its Characteristics Matter  anything with mass and takes up space Mass  measure of mass independent of gravity Weight  measure of amount of matter that depends on the effect of gravity on it

5. Matter  100 Elements  Atoms (submicroscopic!)

6. Why Chemistry Matters Structure, composition, and behavior of matter can be observed, analyzed, and explained on a submicroscopic level Chemistry studies submicroscopic matter in order to explain macroscopic events
