Pure SubstancesElement:

-only one type of atom

-simplest form of matter retaining its properties

Examples:Carbon (C)Helium (He)Gold (Au)

(cannot be separated) (chemically or physically)

Pure Substances

Compound:

different elements chemically bonded together

Examples:Carbon Dioxide (CO2)Water (H2O)Salt (NaCl)Sucrose (C12H22O11)

(can be separated… chemically)

Mixtures

Heterogeneous Mixture:

physically mixed unevenly…can see the different parts

Examples: SandGraniteWood

2 Types:Suspensions & Colloids
