Matter

• Anything that has a mass and a volume

3

Solid
Liquid
Gas
Plasma

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.

5
Atoms

• 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.

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.

Solutions

• Solutions are groups of molecules that are mixed
  up in a completely even distribution.

Homogeneous

• Uniform Distribution.
• Example Sugar and Water

9
Solute

• The substance to be dissolved.

Solvent

• The one doing the dissolving.

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

• 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.

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
