| Mass | The amount of matter in an object – measured in grams (g) |
| Volume | The amount of space an object takes up – measured in cubic centimeters (cm3) or milliliters (mL) |
| Density | The mass of a known volume of a substance – measured in grams per cubic centimeter (g/cm3) |
| Physical Property | A property that does not change the appearance of the substance when tested, Ex: Density, Luster |
| Chemical Property | A property that describes how a material reacts with another substance, EX: Reaction with acid or heat |
| Element | A substance that cannot be broken down into a simpler substance either chemically or physically |
| Atom | A tiny particle that makes up elements |
| Molecule | Two or more atoms of an element held together by bonds EX: O3, C2, H2O |
| Compound | A type of molecule when two or more different types of atoms are held together by bonds EX: H2O, CuSO4, CO2 |
| Chemical Bond | Energy connections that hold atoms together to form molecules |
| Chemical Reaction | Occurs when the atoms and molecules of 2 or more substances rearrange to form a new substance. |
| Reactants | The “starting” or initial materials in a chemical reaction |
| Product | A substance that is formed as a result of a chemical reaction |
| Solubility | The amount of a solute (salt) that will completely dissolve in a given amount of a solvent (water) |
| Saturated Solution | A solution that has the maximum amount of a solute (salt) dissolved in it at a specific temperature and pressure |
