7. Pure Substances Definition: Made up of only ONE kind of matter Ex: sugar, salt, iron, aluminum, copper Pure Substances will ALWAYS have the same properties!! Ex: water will always be water, no matter what it is mixed with

8. Elements Definition: Pure substances that cannot be broken down There are about 100 elements (look on the periodic table)

9. Compounds Definition: A pure substance formed from two or more elements Substances cannot be separated easily Do not get this confused with a mixture!! In a mixture, the substances can ALWAYS BE SEPARATED!!!
