| A | B |
| Matter | Anything with Mass and Volume |
| Element | Material made of only one type of atom |
| Compound | Material made of 2+ atoms chemically bonded together |
| Atom | Smallest part of an element. Building block of matter. |
| Molecule | Smallest part of a compound. |
| Ionic | Give/Take of electrons. Made of a Metal + Non-metal. |
| Covalent | Shared Electrons between 2+ Non-Metals. |
| Metal | Conductive, Shiny, Bendable, Mostly Solids, Positive Ions. |
| Non-Metal | Dull, Brittle, Mostly Gases, Negative Ions. |
| Metalloids | Elements between Metals and Non-Metals, has parts of both. |
| Heterogeneous | Mixtures not evenly spread throughout. |
| Homogeneous | Mixtures evenly spread throughout, AKA Solution. |
| Solvent | Dissolves the Solute. |
| Solute | Dissolved into a Solvent. |
| Colloid | Medium particles dispersed within another. Not even, but stable. |
| Suspension | Large particles temporarily mixed within another substance. |
| Solution | Small particles evenly mixed in another. |
| Acid | ph < 7, dissolves metals, H+ Ions |
| Base | pH > 7, dissolves organics, OH- Ions. |
| Neutral | pH = 7, H+ Ions = OH- Ions. |
