| Heterogeneous mixture that has visible particles temporarily mixed in liquid | suspension |
| Anything that takes up space | Matter |
| characteristic that helps distinguish one kind of matter from another | property |
| cannot be broken down into simpler components and still maintain the properties of the original substance ( element or elements) | Substance |
| has all the atoms in the substance alike | element |
| substance made of 2 or more elements chemically combined | compound |
| material made up of 2 or more substances that can be easily separated by physical means | Mixture |
