Describing atoms, molecules, and matter
| Term | Definition |
|---|---|
| Atoms | They are things made up of a nucleus, protons, and neutrons |
| Molecules | They are a bundle of specific types of atoms put together to form this. |
| Matter | This is made up of molecules and atoms; they also take up space and have mass. |
| Elements | is when one or more atoms of the same kind are bonded together. |
| Compounds | are when two or more different atoms get bonded together. |
| Pure Substance | Is a substance that is made up of one type of atom and can not be separated using physical means (must be chemically separated). |
| Mixture | A substance made up of multiple types of matter and has a variable composition, this mixture can be separated using physical means. |
| Homogeneous Mixture | A mixture where the particles are evenly distributed are also considered solutions |
| Heterogeneous Mixture | A mixture where the particles are not evenly distributed throughout the mixture. |
| Solution | A mixture containing atoms, ions, or molecules fully dissolved |
| Colloid | A mixture containing mid-size particles that do not settle out |
| Suspension | A mixture containing particles that settle out if left undisturbed |
| Tyndall Effect | dispersed colloid particles scatter light, allowing us to differentiate between colloids and solutions |
