| Alkaline Earth Metal | An element in Group 2 of the periodic table.,  |
| Boiling Point | The temperature of which the vapor pressure of a liquid is just equal to the external pressure of the liquid.,  |
| Coefficient | Number placed in front of a chemical formula in an equation that indicates how many atoms or molecules of each reactant and product are involved in a reaction,  |
| Density | The state or quality of being dense; compactness; closely set or crowded condition.,  |
| Electromagnetic Radiation | energy that travels through space in the form of electromagnetic waves.,  |
| Frequency | The number of complete waves that passes a given point in a certain amount of time.,  |
| Hydrate | Is a term used in inorganic chemistry and organic chemistry to indicate that a substance contains water. The chemical state of the water varies widely between hydrates, some of which were so labeled before their chemical structure was understood.,  |
| Ionic Bond | The attraction between two oppositely charged ions.,  |
| Magnetism | The force of attraction or repulsion of magnetic materials.,  |
| Noble Gas | An element in Group 18 of the periodic table.,  |
| Phases | The three forms, or states, of matter- solid liquid and gas.,  |
| Radiation | Process where energy is emitted as particles or waves.,  |
| Solid | Of definite shape and volume; firm; neither liquid nor gaseous; "ice is water in the solid state",  |
| Synthesis Reaction | A synthesis reaction occurs when chemical reactions occur to obtain products on purpose. This means that the process can happen again and is reliable.,  |
| Velocity | Speed in a given direction.,  |
