3. Mixtures and Pure Substances
A pure substance is made of only one kind of material and has definite properties.
Matter that consists of two or more substances mixed together but not chemically combined is called a mixture.

4. Pure Substances:
Elements are the simplest pure substance. Examples: hydrogen, carbon, and oxygen.
The smallest particle of an element that has the properties of that element is called an atom.

5. Pure substances:
Compounds are pure substances that are made of more than one element bound together. Examples: water (H2O), and carbon dioxide.
A molecule (or a Formula Unit) is formed when two or more atoms combine. Example: water (H2O), O2

6. MIXTURES Heterogeneous vs. Homogeneous
Homogeneous matter (solutions): matter that has identical properties throughout. Examples: Salt water, and whipped cream
Heterogeneous matter: matter that
has parts with different properties. Examples: granite, soil, potpourri
