| Mixture | Matter that consists of two or more substances not chemically combined. |
| Pure Substance | A substance made of only one kind of material having definite proportional amounts and properties. |
| Element | The simplest type of pure substance. |
| Compound | Two or more elements chemically combined. |
| Homogeneous Mixture | Two or more substances not chemically combined, but appearing to be evenly blended. |
| Heterogeneous Mixture | Two or more substances not chemically combined, and appearing non-uniform with physically distinct substances included. |
