| Brittle solids and gases to the left of the stair-step line that are dull and bad conductors. | nonmetal |
| An element that shares properties with both the metals and nonmetals. | metalloid |
| A family of elements vertically in the Periodic Table that share many characteristics. | group |
| A row on the Periodic Table whose elements make a gradual change accross it. | period |
| A substence made up of only one type of atom. | element |
| Metals in groups 3-12 whose number of valence electrons is not equal to the group number. | transition elements |
| Groups 1, 2, and 13-18 whose number of valence electrons is equal to the group number. | representative elements |
| Atoms cannot be created or destroyed, so chemical equations must be balanced to be true. | Law of Conservation of Matter |
| Molecules that are made up of only one type of atom. | element molecule |
| Molecules made up of more than one type of atom. | compound molecule |
| The substances that are put through a chemical change. | reactants |
| The substance that results from a chemical change. | products |
| A way of writing what goes on during a chemical reaction. | chemical equation |
| A faster way of writing the type and quantity of atoms and molecules present. | chemical formula |
| Tells the number of molecules of one type of molecule. | coefficent |
| Tells the number of a certain type of atom in a molecule; chemically bonded, can't change. | subscript |
| The production of a compound by means of a reaction of simpler materials. | synthesis |
| The breaking down of compounds into simpler compounds or pure elements. | decomposition |
| A type of chemical reaction in which an element moves out of one compound and into another. | single replacement |
| A chemical reaction in which a molecule trades an atom for a different atom from another molecule. | double replacement |
| A change in an object's velocity. | acceleration |
| A force that does not cause an object to move because there is an equal force on the opposing side. | balanced force |
| The corse an object moves along. | direction |
| A push or pull. | force |

| A galaxy with no spiral structure or elliptical shape. | irregular galaxy |
| A galaxy with a spiral structure and a central bulge. | spiral galaxy |
| A space measure defined by the distance light travels in a year. | light year |
| Bodies composed of rock and metal that orbit the Sun mainly in a belt between Mars and Jupiter. | asteroid |
| Small bodies of ice, rock, and cosmic dust with tails that orbit the Sun in elliptical pathways. | comet |
| A meteoroid that enters a celestial body's atmosphere. | meteor |
| A meteoroid that strikes the surface of a celestial body. | meteorite |
| A particle of rock and metal smaller than an asteroid that floats in outer space. | meteoroid |
| A creation theory that says an explosion created the universe about 14 billion years ago and it has been expanding ever since. | Big Bang Theory |
