The Learning Period
•Elements
• All
elements are
made of atoms.
• Atoms of the
same element are
alike.
• Atoms of different
elements are
different.
•Compounds
Compounds are also
pure substances.
• But compounds are
made from more
than one element.
• Water is a
compound.
• Water can be
broken down into
simpler substances –
hydrogen and
oxygen.
•
•A mixture is a
combination of two or
more substances where
there is no chemical
combination or reaction.

•Mixtures combine
physically in no specific
proportions.
They just mix.

In a colloid the
particles are mixed
together but not
dissolved.
• The particles are
relatively large and
are kept
permanently
suspended.
•
•Colloids
A colloid will not
separate upon
standing.
• The particles are
constantly colliding,
and this allows a
colloid to scatter
light – thus colloids
often seem cloudy.
•
Heterogeneous Mixtures (cont.)
Colloids are heterogeneous mixtures of
intermediate sized particles (between 1
nm and 1000 nm) and do not settle out.
Colloids are categorized according to the
phases of their particles.
Heterogeneous Mixtures (cont.)
•Section 14-1
SOLUTIONS
•Solutions
A solution is a type of homogeneous mixture
formed when one substance dissolves in
another.
• It is the best mixed of all mixtures.
• A solution always has a substance that is
dissolved and a substance that does the
dissolving.
• The substance that is dissolved is the solute
and the substance that does the dissolving is
the solvent.
•
•Ocean water is a solution
•The universal solvent: Water
•Water as a solvent
• Many
liquid solutions contain water as
the solvent.
• Ocean water is basically a water
solution that contains many salts.
• Body fluids are also water solutions.

Homogeneous Mixtures (cont.)
•Section 14-1
SUSPENSIONS
Suspension- a heterogeneous mixture in which
the particles are large enough to be seen by a
microscope or the unaided eye (eventually, they
settle out of the mixture). Example: stirring a
teaspoon of dirt in a glass of water.

MAKE A PREDICTION…..
WHAT DO YOU THINK THE DIFFERENCES
BETWEEN HOMOGENOUS &
HETEROGENOUS MIXTURES ARE ?
•Is it uniform throughout?
• If
the answer is no, the matter is a
heterogeneous mixture.
Considered the “least mixed.”
• Does not appear to be the same
throughout.
• Particles are large enough to be seen and
to be separated from the mixture.
•
•Examples of heterogeneous
mixtures
• Sand
and pebbles
• Oil and water
• Powdered iron and powdered sulfur
•Examples of heterogeneous
mixtures
• Sand
and pebbles
• Oil and water
• Powdered iron and powdered sulfur
•Is it uniform throughout?
• If
the answer is yes, the matter is
homogeneous (looks the same
throughout).
• That leads us to another question.
•Homogeneous Mixtures
•A
mixture that appears to be the same
throughout.
• It is “well mixed.”
• The particles that make up the mixture
are very small and not easily
recognizable.
•Examples of homogeneous
mixtures
Milk, toothpaste, and mayonnaise are homogeneous
mixtures. They are also colloids.

WHAT HAPPENED TO THE MILK ?
Mixtures, elements, compounds
• Scientists
like to classify things.
• One way that scientists classify matter is
by its composition.
• Ultimately, all matter can be classified
as mixtures, elements and compounds.
By asking these questions scientists can classify
matter into:
• Mixtures – two or more substances that are
not chemically combined with each other
and can be separated by physical means.
The substances in a mixture retain their
individual properties.
•
Solutions – a special kind of mixture where one
substance dissolves in another.
Elements – simplest form of pure substance.
They cannot be broken into anything else by
physical or chemical means.
• Compounds – pure substances that are the
unions of two or more elements. They can be
broken into simpler substances by chemical
means.
•
•Elements
• All
elements are
made of atoms.
• Atoms of the
same element are
alike.
• Atoms of different
elements are
different.
•Elements
• In
1813, a system
of representing
elements with
symbols was
introduced.
•
•
Each symbol consists of one
or two letters.
Two letters are needed for a
chemical symbol when the
first letter of that element’s
name has already been
used.
•Compounds
Compounds are also
pure substances.
• But compounds are
made from more
than one element.
• Water is a
compound.
• Water can be
broken down into
simpler substances –
hydrogen and
oxygen.
