1. Properties of Matter
Chapter 16

2. Matter
Substances
elements
Compounds
mixtures
Homogeneous mixture
Heterogeneous
mixture

3. Classifying Matter: matter can be
classified into two main types
 Mixture
 contains more than
one kind of matter that
can be separated by
physical means
 Pure Substances
 is matter that cannot
be separated by
physical means
sugar
Trail mix

4. Two Types of substances
 Elements
 has one kind type of
atom
 examples:
 helium (He)
 carbon (C)
 hydrogen (H)
 oxygen (O)
 Compounds
 a substance that
contains more than one
type of atom
 examples:
 H2O (pure water)
 NaCl (sodium chloride)

5. Matter
Examples of elements:
gold
aluminum
mercury
iodine

7. Examples of pure substances that are
compounds
Water =H2O
NaCl = table salt
Sugar = C6H12O6

8. Basic units of substances are
always in motion
Atom
is the smallest possible particle of an
element
Molecule
is the smallest particle of the compound that
retains the properties of the compound

9. HETEROGENOUS MIXTURE
 a mixture which has non-
uniform composition
throughout it’s mass.
 the particles are visible in
the eyes.

10. Heterogenous Mixture
 oil and water

11. Heterogenous Mixture
Mixed salad

12. Heterogenous Mixture
Water and sand

13. HOMOGENEOUS MIXTURE
 a mixture which has
uniform composition
throughout it’s mass.
 the particles are NOT
visible in the eyes.

14. HOMOGENEOUS MIXTURE
rainwater

15. HOMOGENEOUS MIXTURE
air

16. HOMOGENEOUS MIXTURE
coffee

17. What type of mixture is it?
heterogeneous
homogeneous
Salt water
