5. 1. Elements are pure substances
made of only one kind of atom.
2. As we have learned, atoms are
tiny structures found in all matter.
3. Most substances contain many
different atoms.
4. It is how those atoms are
arranged that determine whether
you have an element, compound
or mixture.
6. 1. One kind of atom
2. Pure (because all particles are the
same)
3. Smallest particle to retain
element’s identity
4. Separated only in nuclear
reactions
7. Particles look like:
Every atom looks
8 exactly the same
8 w/ the same
8 number of protons
Oxygen
1
1
1
Hydrogen
8. Example:
Aluminum: Every
atom of aluminum
in this can is
exactly the same
Your Example?
9. 1. Two or more kinds of atoms
chemically bonded
2. Pure (because all particles are the
same)
3. Smallest particle to retain the
Compound’s identity (SET RATIO of
particles)
4. Separated or rearranged in
chemical reactions C O
2
10. Particles look like: Every compound
looks exactly the
same w/ the same
set ratio
Carbon Dioxide –
CO2
Sodium Chloride -
NaCl
11. Example:
Salt: Every
molecule of the
compound NaCl is
exactly the same
Your Example?
12. 1. Two or more elements and/or
compounds blended together
physically
2. Not pure (because all the
particles are not the same)
3. Separation through distillation,
magnetic, evaporation, density,
or particle size
4. No set ratio
13. Particles look like:
Each particle keeps its
own identity….they are
just “blended” together
Mixture #1
Mixture #2
14. Examples: Heterogeneous: Different
components are easy to see in this
type of blending
Homogeneous: Different components
are difficult to see because they are
evenly distributed
Your Examples?
19. 1. A solution is a mixture where all the
components blend together to look
like one substance.
2. A solution is a homogeneous mixture
that appears to be a single
substance.
3. 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. In solutions, the SOLUTE is the substance
that is being dissolved and usually is the
smaller quantity in the mixture.
2. The SOLVENT is the substance in the
solution doing the dissolving and is
usually the larger quantity in the mixture.
3. It is the SOLVENT that is doing the
dissolving.
4. Go to page 144-145 in your textbook:
Give examples of solutions in various
states.
21. • Homogeneous: 2 or more
things evenly blended and
disappear into each other.
• Solute – Smaller quantity by %
• Solvent – Larger quantity by %
• Solution – a homogeneous
mixture
22. • Heterogeneous: 2 or more
things put together and still
can be seen.
• No set RATIO.
23. Have you ever put sugar into
lemonade and seen 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.
24. Saturation Level What does this What does this look
mean? like? (color)
Unsaturated •Mixture contains more
solvent than solute
•Able to dissolve more
solute
Saturated •Mixture contains the %
of solute completely
dissolved by solvent
•No able to dissolve
more solute
Supersaturated
•Mixture contains the %
of solute unable to be
dissolved by the % of
solvent at the given
temp.
High temp usually = higher solubility
25. 1. We now know the definition of
Element, Compounds & Mixtures
2. What do their particles look like?
