Matter Unit Vocab
Matter Unit Vocabulary
| Question | Answer |
|---|---|
| atom | The smallest particle of an element. |
| element | A substance that is made up of only one type of matter. Atoms of one element are all alike. |
| molecule | The smallest whole part of a compound. Atoms of elements can also be grouped to form a molecule. |
| compound | A substance made when two or more elements are joined together and lose their properties. |
| solid | A phase of matter that has a definite shape and definite size. Particles in a solid are tightly packed and vibrate slightly. The particles are arranged in order. |
| liquid | A phase of matter that takes up a definite amount of space but has no definite shape. Particles in a liquid are close together and slide past each other. The particles are not arranged in order. |
| gas | A phase of matter that does not take up a definite amount of space and has no definite shape. Particles in a gas are moving very fast and in all directions. |
| mixture | Two or more types of matter that are mixed together but keep their own properties. Matter in a mixture is not evenly distributed. |
| solution | Mixing of two or more types of matter where one substance dissolves (mixes evenly) in the other substance(s). Each keeps its own properties. |
| proton | Positively charged particles in the center (nucleus) of the atom. Each element has a different numbers of protons than any other element. |
| neutron | Particles in the center (nucleus) of the atom. They have no charge. Each element has a different number of neutrons than any other element. |
| electrons | Negatively charged particles that move around the center of the atom in orbital shells. Each element has a different number of electrons than any other element. |
| nanotechnology | The technology of manipulating matter at the atomic level to create products. |
| matter | Anything that has mass (made of particles), takes up space, and cannot be created or destroyed. |
| temperature | The measure of heat energy present. |
| boiling point | The temperature at which a liquid changes to a gas. |
| freezing point | The temperature at which a liquid changes to a solid. |
| evaporation | The process of a liquid changing to a gas. |
| condensation | The process of a gas changing to a liquid. |
| dependent variable |
