Matter
can be divided into two categories
Pure Substances
All the
particles
are the
same.

Mixtures
There are different
types of particles mixed
together.
Pure Substances
can be divided into two categories
Elements
The atoms that make up
the particles are
identical.

Elements
The atoms that make up

identical.
Compounds
The particles are made
of different atoms
bonded together.
Elements
All elements (the different types of atoms) are
listed on the Periodic Table.
Mixtures
can be divided into two categories
Heterogeneous
The different parts are
visible and can be
separated mechanically.

Homogenous
The
different
parts
are not
visible.
Suspension
• A Heterogeneous mixture made of a liquid ans
solid particles that settle.
• Example: River Water
• P. 466 draw figure 7
Colloid
• A heterogeneous mixture whose components
never settle.
• Example: Milk, smoke, fog
• Particles are large enough to scatter light
(Tyndall Effect)
Solution
• The same thing as a homogeneous mixture
• A solute is dissolved in a solvent
• Examples: Kool-aid, coffee, tea, air, gasoline,
steel
