| Density | Never Changes |
| Distillation | Physical means of separating substances |
| Constituent Element | Identity |
| Colloid | Type of heterogeneous mixture (hard to see) |
| Mixture | easily separated (sand and water) |
| aerosols | air part of combination (air leaves substance after spray) |
| Sols | behave like solutions |
| Solutions | aerosols, ionic, sols, covalent (look like pure substance) |
| Compound (molecule) | 2 or more atoms combine together (H2) (H2O) |
| Element | Substance made up of atoms |
| Heterozygous | Different Kind (mixture) |
| Homogeneous | Same Kind (pure) |
| Ions | Cannot get through membrane, because they have a charge |
| Chemical Change | change matter |
