6. What’s (the) Matter? Anything with mass and volume
can be classified as pure or impure

7. Mixtures (Impure) Substances are being mixed together
they are not chemically bonding to one another.

8. Mixtures

9. What kind of mixtures are there?
Heterogeneous mixtures
Mixtures that are not uniform throughout.
Sometimes individual parts can be seen.
Ex. Cookie Dough

11. What kind of mixtures are there?
Homogeneous mixtures
The same throughout, it’s well mixed.
Ex. Milk
Can be solutions or suspensions
Made of 2 parts
Solute: stuff being dissolved (smaller amount)
Solvent: stuff doing the dissolving (larger amount)

12. Solutions (Impure) All found in single phase
Example: Salt water is liquid, white gold is made of gold and palladium

13. Suspensions (Impure)
Solute and solvent are found in different phases of matter
Examples:
Milk is made of water, solid proteins
Blood is made of water, solid proteins

14. What’s not a mixture? Pure Substances Made of one kind of material
Have definite properties.

15. Pure Substances Elements Are made up of atoms
Atoms - Smallest particle of an element that has the properties of that element
each element has its own unique atoms
an element’s atoms are identified by its protons
Are represented by their atomic symbols : O, Na, Cu, H, He

16. Pure Substances Compound
Compound- a substance in which two or more elements are combined with a chemical bond
Shown with chemical formulas
tell us the number and type of each atom in a compound

17. Pure Substances Molecule
a molecule is the smallest particle of a compound.
Example: H2O
