| What is the unit for energy? | joules |
| What subatomic particles are in the nucleus of the atom? | protons and neutrons |
| What is an ion? | an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. |
| Why are blue colored flames best on a bunsen burner? | they are clean, hotter, and safer |
| What is the volume of a liquid measure in? | ml |
| How can I turn and orange flame into a blue flame on a burner? | open the air hole |

| What is the equation for speed? | distance/time |
| What kind of boundary is the San Andreas fault on? | strike-slip, transform |
| Two nonmetals bonded together are what kind of compound? | Covalent compound |
| If an atom has one valence electron, what would its charge be when it becomes an ion? | -1 |
| Where are the metalloids located? | stair step between nonmetal and metal |
| What is the process of how the Earth was formed called? | accreation |
| What are covalent bonds? | share electrons, made of non-metals only |
