Atoms and Molecules
| Definition | Answer |
|---|---|
| COMPOUND | Two or more elements that are chemically combined and whose properties are different from each of the elements in it. |
| MIXTURE | Two or more elements that are combined in a way that chemical reactions do not occur; can be taken apart. |
| PURE SUBSTANCE | A substance made from a single type of atom or one type of molecule; can be a compound or a single element; Examples: diamonds, salt, gold |
| ELEMENT | A pure substance that is the building block of all matter. |
| BONDED | Atoms are held together by a force of attraction |
| SOLUTE | A substance that is dissolved in another substance |
| SOLVENT | The liquid in which a solute is dissolved |
| SOLUTION | Substances in a mixture are evenly distributed; all parts are the same. |
| HOMOGENEOUS MIXTURE | A mixture that has the same combination of components (parts) throughout the entire mixture; Examples: sugar in water |
| HETEROGENEOUS MIXTURE | A mixture that is not the same throughout; can be separated; Examples: sand in water |
| MATTER | Anything that has a mass and a volume |
| ATOMS | The building blocks of matter; made up of protons, electrons, and neutrons |
| MOLECULES | Two or more atoms are joined together chemically; the elements can be different or the same |
| FILTRATION | Process of separating a mixture by using a funnel and filter paper to separate a solid from a liquid |
| DISTILLATION | Process in which the parts of a substance or liquid mixture are separated by heating it to a certain temperature and then condensing the resulting vapors |
| EVAPORATION | A method of separating a mixture where the liquid turns into a gas and the solid residue is left behind |
| MAGNETISM | A method of separating a mixture by removing metals from non-metal substances |
| SIFTING | A method of separating a mixture that uses a screen-like device or mesh device to separate larger objects from smaller objects |
