| Atoms | Smallest unit particle of an element. |
| Ball-and-Stick Model | A type of model used to show how some atoms are connected. |
| Chemical Formula | The symbolic representation of the partials of a pure substance. |
| Chemical Symbol | The easy to write format that molecules and atoms are typically expressed in. |
| Compound | Two or more elements in a stable amount that can be broken down through a chemical means. |
| Distillation | A physical means of separating a mixture by heating the liquid to its boiling point to remove the liquid and leave behind another substance. |
| Distilled Water | Pure water lacking any impurities. |
| Element Symbols | The short hand method of writing an element with the first letter capitalized and the second in lower case (when applicable). |
| Element | A pure substance that cannot be broken down any further thorough chemical or physical means. |
| Filtration | A physical means of separating a mixture by using a porous medium to allow the liquid to flow through however not the solid within. |
| Gases | State of mater when molecules are spaced out as much as possible. It has not definite shape or volume. |
| Heterogeneous | A sample of matter that does not appear uniform throughout where it be in distinctive phases or visible to the naked eye. |
| Homogenous | A sample of matter that appears uniform throughout. |
| Kinetic Molecular Theory | States that all matter is composed of extremely tiny particles that are in constant motion. |
| Law of Definite Composition | States any compound is always made up of elements of the same proportions by mass (weight). |
| Liquids | State of matter when molecules have some attractive force between them; it has a definite volume but not a definite shape. |
| Macroscopic | Things that can be seen by the unaided eye |
| Matter | Anything that has mass. |
| Microscopic | Things that have that have are too small to be seen without an aided eye. |
| Mixture | A sample of matter that consists of two or more chemicals. |
| Model | A representation of something else. |
| Molecule | The smallest individual particle that is present in one kind of matter. |
| Particulate | The extremely tiny particles that make up all matter. |
| Periodic Table of Elements | A list of names and symbols of all the elements and includes additional information about each element. |
| Pure Substance | A single chemical or one kind of matter. |
| Solid | State of matter when the molecules are closely packed together and there is little room to vibrate; it has both a definite shape and volume. |
| Solution | A homogenous mixture of two substances that are in the same phase. |
| Space –Filling Model | Shows the outer boundaries where that the particle will fill. |
| States of Matter | When a substance has uniform composition and appearance. |
