Matter

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
YES
NO
YES
NO
11
If matter can NOT be separated by physical means.

• It is a SUBSTANCE
• If the substance cant 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, it is a
  COMPOUND, made of two or more different kinds of
  atoms chemically bonded together.
• Ex. Water (2 Hydrogens and 1 oxygen)

13
YES
NO
YES
NO
Yes
NO
14
ELEMENTS can be.

• MONATOMIC single atoms Al
• DIATOMIC two of the same atom bonded
  together in pairs O2
• POLYATOMIC three or more of the same atom
  bonded together O3

7 Diatomic Elements

Review

• What is
• MATTER
• SUBSTANCE
• MIXTURE
• ELEMENT
• COMPOUND
• HETEROGENEOUS VS. HOMOGENEOUS

18
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?

19
SODA

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