13. Particles of Elements, Compounds, and Mixtures
Chapter 9
Today’s Goal:
I can distinguish the particle arrangement between elements, compounds, and mixtures.
I can identify the different parts of a solution.
I can differentiate between a heterogeneous and homogeneous mixture.

14. Types of Mixtures…
Solution
Colloid
Suspension
SOLVENT
SOLUTE

15. Solution:
This is a homogeneous mixture…it’s the same all throughout.

16. Homogeneous vs. Heterogeneous
Homogeneous—mixture is the same all throughout (Ex: Solutions like lemonade)
Heterogeneous—mixture where particles remain physically separate (Ex: Salad, Bag of M&Ms)

17. ELEMENTS

18. Mixture of Elements

19. Compounds

20. Mixture of Compounds

21. Mixture of Elements and Compounds

22. At your lab table…
Look at each diagram and identify it as one of the following:
1) Element
2) Compound
3) Mixture—It can be a mixture of
elements, a mixture
of compounds, or a
mixture of compounds
and element.

23. Let’s review… This model of water would be more accurate if
The hydrogen atoms were drawn larger than the oxygen atom
The hydrogen atoms were shown to be various sizes
There was one less hydrogen atom
There was one more oxygen atom

24. Let’s review…
2. When sodium, a soft metal, is combined with chlorine, a poisonous gas, salt is formed. Which statement is true about this combination?
Sodium and chlorine combine physically to form a new substance that retains the properties of the original substances.
Sodium and chlorine combine chemically to form a new substance with new properties.
Salt maintains some, but not all, of the physical properties of sodium and chlorine.
Salt can be easily separated back into sodium and chlorine.

25. Let’s review…
3. Which chemical cannot be further broken down into other chemicals using ordinary laboratory processes? 1 2 3 4

26. Let’s review…
Based on the information in the table, which mineral is also an element?
Graphite
Quartz
Calcite
Hematite
