2. Matter
Anything that has a mass and a volume

3. States of Matter Solid Liquid Gas Plasma
Close up view of atoms and their behavior

4. Physical vs. Chemical Change
Changing from one state to another is a
Physical Change.
If a new substance is formed it is a
Chemical Change.
Images are from

5. Atoms Elements The building blocks of Matter
Consists of Protons (+), Electrons (-),
and Neutrons (N).
Elements
Consists of only one kind of atom,
Cannot be broken down into a simpler type of matter by either physical or chemical means
Can exist as either atoms or molecules.
Images are from

6. Molecules
A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.
In the animation above, two nitrogen atoms
(N + N = N2) make one Nitrogen molecule .

7. Compounds Atoms of two or more different elements bound together.
Can be separated into elements chemically, but not physically.
In the animation above, water (H20) is a compound made of Hydrogen and Oxygen.

8. Solutions Homogeneous
Solutions are groups of molecules that are mixed up in a completely even distribution.
Homogeneous
Uniform Distribution.
Example: Sugar and Water
Images are from

9. Solute Solvent The substance to be dissolved.
The one doing the dissolving.
Images are from

10. Making a Solution

11. Colloids
Particle sizes are in between the size of particles found in solutions and suspensions .
Can be mixed and remain evenly distributed without settling out.

12. Mixtures Heterogeneous
They are substances held together by physical forces, not chemical.
Can be separated physically.
Solutions are also mixtures.
Heterogeneous
The substances are not uniformly mixed.
Example: Sand in a glass of water.
Images are from

13. Mixtures Suspensions Are heterogeneous mixtures consisting of parts
that are visible to the naked eye.
Substances will settle over time.
Example: the ingredients in salad dressing
