4. Elements are pure substances made of
only one kind of atom.
1.
As we have learned, atoms are tiny
structures found in all matter.
2.
Most substances contain many
different atoms.
3.
It is how those atoms are arranged
that determine whether you have an
element, compound or mixture.

5. 1.
2.
3.
4.
One kind of atom
Pure (because all particles are the same)
Smallest particle to retain identity of the
element
Separated only in nuclear reactions

6. Particles look like:
8
Every atom looks
exactly the same
w/ the same
number of protons

Oxygen

Hydrogen

7. Example:
Aluminum: Every
atom of aluminum
in this can is
exactly the same
Your Example?

8. 1.

3.
4.
Two or more kinds of atoms chemically
bonded
Pure (because all particles are the
same)
Smallest particle to retain the identity of
the compound (SET RATIO of particles)
Separated or rearranged in chemical
reactions
CO
2

9. Particles look like:
Every compound
looks exactly the
same w/ the same
set ratio
Carbon Dioxide –
CO2
Sodium Chloride NaCl

10. Example:
Salt: Every
molecule of the
compound NaCl is
exactly the same
Your Example?

11. 1.
2.
3.
4.
Two or more elements and/or compounds
blended together physically
Not pure (because all the particles are
not the same)
Separation through distillation, magnetic,
evaporation, density, or particle size
No set ratio

12. Particles look like:
Each particle keeps its
own identity….they are
just “blended” together
Mixture #1
Mixture #2

13. Examples:
Heterogeneous: Different
components are easy to see in this
type of blending
Your Examples?
Homogeneous: Different components
are difficult to see because they are
evenly distributed

14. 1.

3.
Based on your notes, LABEL the illustrations
as Elements, Compounds or Mixtures
Then, Write the letters A, B, C, D or E from the
pictures to match their description.
Classify the pictures as(CROSS OUT
MOLECULE)
• ATOM
• COMPOUND
• ELEMENT

16. Compound

18. Mixture

19. 1.
2.
3.
A solution is a mixture where all the components
blend together to look like one substance.
A solution is a homogeneous mixture that appears to
be a single substance.
The solution is composed of particles of two or more
substances that are distributed evenly among each
other and have the same appearance and
properties throughout.

20. 1.
2.
3.
4.
In solutions, the SOLUTE is the substance that is being
dissolved and usually is the smaller quantity in the
mixture.
The SOLVENT is the substance in which the solute is
dissolved and usually is the larger quantity in the
mixture.
It is the SOLVENT that is doing the dissolving.
Go to page 144-145 in your textbook:
• A) Copy example in Book
• B) Give your own example – Groups can have the
same example

21. Topic: Solutions (next 5 slides)
Name
Date
Period
Homogeneous
• 2 or more things evenly blended
and disappear into each other
Solute
• Smaller quantity by %
Solvent
• Larger quantity by %
Solution
• Homogeneous mixture
Examples
1) Dish soap
2) (your example)

22. Heterogeneous
• 2 or more things put together
(blended) but still can be
individually seen
• No set Ratio
Example
1) Salad, Pizza, Trail Mix, Hamburger,
Taco
2) (your example)

23. Saturation Level What does this
mean?
Unsaturated
What does this look
like? (color)
•Mixture contains more
solvent than solute
•Able to dissolve more
solute
Saturated
Supersaturated
•Mixture contains the %
of solute completely
dissolved by solvent
•Not able to dissolve
more solute
•Mixture contains the %
of solute unable to be
dissolved by the % of
solvent at the given
temp.
High temp usually = higher solubility

24. Have you ever put sugar put into
lemonade and see the grains of
sugar sink to the bottom and not
dissolve?
This is because the lemonade
(solution) is supersaturated. In
other words, there is not enough
water (solvent) to completely
dissolve the sugar (solute).
Temperature and Pressure can
affect saturation levels.

25. 1. We now know the definition of
Element, Compounds & Mixtures
2. What do their particles look like?
