The smallest particle into
which an element may be
divided and still be the
Anything that occupies
space and have mass .
Energy is NOT matter
Matter is divided into 4
All elements are on the Periodic Table
All matter is made of an element or a
combination of elements
Hydrogen, Oxygen, Gold
A substance that consists of only one
kind of atom and that cannot be
chemically separated into other
Elements cannot be changed into simpler
substances by any chemical process .
Elements are made up of atoms .
Simplest kind of matter
Cannot be broken down into simpler
All one kind of atom.
There are 109 of these known to
that can be broken down
by chemical methods
When they are broken down, the
pieces have completely different
properties than the compound.
Made of molecules- two or more
They are pure
can be mixtures!
ELEMENTS contain only one kind of
There are 109 different kinds of
1-109 = atomic # of the elements.
Solutions - A special mixture formed
when one substance dissolves in another .
- The most abundant
substance in the solution .
- The least abundant
substance in the solution .
All solutions are not liquids :
Air is a solution of gases .
Steel is a solution of metals .
Mixed molecule by molecule Solutions
Can occur between any state of matter.
Solid in liquid- Cool-aid
Liquid in liquid- anti freeze
Gas in gas- air
Solid in solid - brass
Liquid in gas- water vapour
Like all mixtures, they keep the
properties of the components.
Can be separated by physical means
Do not scatter light!
Not easily separated But can be separated.
Two techniques for separating
changing from a
liquid to vapor
Process used to drive
vapor from liquid by
Great for separating
two or more liquids

Matter that can be

It is two or more
kinds of matter that

Matter that consists of two or more
substances mixed together: but not
chemically combined or bonded.
Examples: concrete, Sea Water, a bag
full of different colored marbles..

Properties of Mixtures :
substance retains its own properties.

What about MOLECULES?
They are the smallest particle of
a substance that still retains the
properties of that substance and is
composed of 2 or more atoms.
