•Anything that has a mass and a volume
Close up view of atoms and their behavior

•Changing from one state to another is a
Physical Change.
•If a new substance is formed it is a
Chemical Change.

• The building blocks of Matter
• Consists of Protons (+), Electrons (-),
and Neutrons (N).
• 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.

• 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 .
• 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 are groups of molecules that are
mixed up in a completely even distribution.
• Uniform Distribution.
• Example: Sugar and Water

• The substance to be dissolved.
• The one doing the dissolving.

• Particle sizes are in between the size of particles
found in solutions and suspensions .
• Can
be mixed and remain evenly distributed without
settling out.
• They are substances held together
by physical forces, not chemical.
• Can be separated physically.
• Solutions are also mixtures.
• The substances are not uniformly mixed.
• Example: Sand in a glass of water.

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