1. Matter Anything that has mass and takes up space (volume) What is NOT matter???

2. Classification of Matter

3. Matter Can it be separated by physical means? If yes….

4. Then you have a Mixture

5. Physical ways to separate a mixture Filtering (particle size) Distillation (boiling point) (dissolved solid)

6. Physical ways to separate a mixture Chromatography (attraction to paper)

7. Is the mixture uniform throughout? IF yes, it is HOMOGENEOUS

8. If no, then the mixture is Heterogeneous

9. Homogeneous vs. Heterogeneous mixtures

10. Matter Can it be separated by physical means? Mixture Is it uniform throughout? Homogeneous Gatorade Bronze Brass Homogenized beverages Heterogeneous Dirt Sea shells Rocky road ice cream Non-homogenized beverages Substance YESNO YESNO

11. If matter can NOT be separated by physical means…. It is a SUBSTANCE If the substance can’t be broken down, it is an ELEMENT Elements are made of only one type of atom Ex. Aluminum, carbon, oxygen

12. SUBSTANCE If the substance CAN be broken down into 2 or more elements, it is a COMPOUND. Compounds are made of two or more different kinds of atoms chemically bonded together.

13. COMPOUND Ex. Water is a compound made of the elements Hydrogen and Oxygen. The RATIO of elements in a compound always stay the same. In WATER the ratio is always 2 Hydrogens to 1 Oxygen, or 2:1

14. Matter Can it be separated by physical means? MIXTURE Is it uniform throughout? Homogeneous Gatorade Bronze Brass Homogenized beverages Heterogeneous Dirt Sea shells Rocky road ice cream Non-homogenized beverages SUBSTANCE Can it be broken down? COMPOUND WATER H20 SALT NaCl ELEMENT Aluminum Graphite (Carbon) YESNO YESNOYesNO

15. ELEMENTS can be…. MONATOMIC : single atoms Al DIATOMIC : two of the same atom bonded together in pairs O 2 POLYATOMIC: three or more of the same atom bonded together O 3

16. 7 Diatomic Elements

17. Particles of Matter

18. Review What is…… MATTER SUBSTANCE MIXTURE ELEMENT COMPOUND HETEROGENEOUS VS. HOMOGENEOUS

19. CHEMISTRY: THE STUDY OF MATTER Did you know that…….. One of the most popular “foods” in the United States is an entirely SYNTHETIC (man-made) mixture. Can you guess what it is?

20. SODA The average person consumes 40 GALLONS (!) of soda each year Mixture: carbonated water sweetener, acids, flavorings, caffeine

21. States of Matter GAS LIQUIDSOLID
