| ionic bond | attraction b/w a metal and a non-metal |
| chemical bond | the attraction between elements in order to become chemically stable. |
| diatomic molecule | when two of the same elements share electrons. |
| Covalent bond | attraction b/w non-metals and non-metals |
| oxidation # | tells the combined ability of the element |
| two things an oxidation # tells you | The charge of the elements and the number of electrons given or taken in order to become chemically stable. |
| polar molecule | A molecule that has oppositely charged ends. |
| nonpolar molecule | A molecule that doesn't have oppositely charged endsA molecule that does not have oppositely charged ends.A molecule that does not have oppositely charged ends. |
| ion | Atoms that have a charge |
| The most common state of matter in the universe | plasma |
| The amount of energy needed to change a material from the liquid state to a gas state at the boiling point | heat of fusion |
| The amount of energy needed to change a material from a solid state to a liquid state | heat of vaporization |
| liquids resistance to flow | viscosity |
| Solids that melt gradually over a wide temperature range | amorphous |
| Archimedes Principal | a rising helium balloon |
| Boyle's law | pumping a tire |
| Charles' Law | heating air in a balloon |
| Bernoulli's Principal | lift in airplanes |
| meniscus is caused because | adhesion being stronger than cohesion. |
