| A | B |
| Saturated | This is when a solvent can't dissolve any more solute |
| Vacuum | This is the absence of matter |
| Mass | The amount of matter in an object (measured in grams) |
| Volume | The amount of space an object fills (cm cubed, or mL) |
| Solute | The substance such as sugar that gets dissolved |
| Solution | A well-mixed mixture, often with one thing dissolved in another |
| Density | How much matter is packed into an object |
| Solvent | A substance, such as water, that does the dissolving |
| Concentration | The amount of a substance in a solution (think kool aid) |
| Nucleus | The center of an atom |
| Compound | Two or more elements chemically combined |
| Mixture | Two or more substances that have been physically combined |
| Proton | Positive particle, found in nucleus |
| Neutron | Neutrally charged particle, found in nucleus |
| Electron | Negatively charged particle, orbits nucleus |
| Ion | A charged atom, with too many or too few electorns |
| Isotope | An atom with too many or too few neutrons |
| Ionic bond | Combination of a non-metal with a metal, and electrons are given or taken. Two ions combine (one positive, one negative) |
| Covalent bond | A non-metal combined with another non-metal, electrons are shared. |
| Atomic Number | The number of protons in an atom |
| Atomic Mass | The weight of an atom (number of protons plus neutrons) Weight in grams needed to have one mole of substance |
| Mole | A number that represents the amount of substance you have. It is equal to 6.022 x 10^23 |
| Graduated Cylinder | Tube with markings used to measure a precise amount of liquid |
| Density greater than one | Object will sink in water |
| Density less than one | Object will float in water |
