12. YOU ARE MADE OF ELEMENTS

13. PARTICLES OF ELEMENTS ATOM- IS THE BASIC PARTICLE FROM WHICH ALL ELEMENTS ARE MADE. KEY- ATOMS HAVE THE ABILITY TO COMBINE WITH OTHER ATOMS. CHEMICAL BOND- WHEN ATOMS COMBINE AND THE FORCE OF ATTRACTION FORMS A NEW SUBSTANCE MOLECULES- GROUPS OF TWO OR MORE ATOMS HELD TOGETHER BY A CHEMICAL BOND. EX-H2O, CO2, …..C12H22O11

14. Copy the Atom

15. Molecules http://apps.theodoregray.com/molecules

16. COMPOUNDS COMPOUND- A SUBSTANCE MADE OF TWO OR MORE ELEMENTS CHEMICALLY COMBINED IN SET RATIO. KEY- WHEN ELEMENTS ARE CHEMICALLY COMBINED THEY FORM COMPOUNDS HAVING PROPERTIES THAT ARE DIFFERENT THAN THE INDIVIDUAL ELEMENTS.

17. Examples

18. MIXTURES MIXTURES- 2 OR MORE SUBSTANCES NOT CHEMICALLY COMBINED. EX- SALAD, SOIL 2 TYPES HETEROGENEOUS MIXTURE- YOU CAN SEE THE DIFFERENT PARTS. EX SALAD HOMOGENEOUS MIXTURE- CANT SEE THE PARTS. EX- SUGAR WATER
