| Term | Definition |

| Periodic Table | This organizer arranges elements according to the element's properties |
| Mercury and Bromine | These two elements are liquid at room temperature |
| Protons | There are approximately 105 elements on the periodic table. Each element is listed as having a unique number of this particle. |
| Mixture | This is the general term given to materials that are made up of two or more substances that are physically combined. |
| As you move down a column in the periodic table this happens to the atomic weight, density, and atomic radius. | Increase |
| Diatomic elements | When elements like H, O, N, Cl, B, I, F are uncombined with other elements that are found only in pairs, they are considered this. |
| These are the noble gases due to the fact that they do not mix with other elements. | Xe, Kr, Rn, Ne, He, Ar |
| Butter can be classified as this type of matter | Homogeneous mixture - It appears the same throughout but can be physically separated. |
| Elmer's glue would be classified as this type of matter | Homogeneous mixture |
| Demitri Mendeleev | The Russian scientist credited with the creation of the modern periodic table. |
| Pure substance | This is the general term given to materials that have a fixed chemical composition and are the same throughout |
| A combination of flour, cocoa, and baking soda would be classified as this type of matter | Heterogeneous Mixture - physically combined and has different properties throughout |
| Atomic Radius | This is the only periodic quality that decreases as you move across a row in the periodic table. |
| Synthesized Elements | The name given to the elements (greater than 93) that have been created through transmutation |
| Trail mix can be classified as this type of matter | Heterogeneous mixture |
| Hot chocolate can be classified as this specific type of matter | Solution - It is the same throughout |
| Metals | More than 80% of the elements are classified as this. |
| Concept Map | This study tool can be especially helpful when learning new terms and can help you better understand how the terms relate to each other. |
| Metalloid Line | This "stair-step" line on the periodic table is called this due to the fact that these elements have properties of both sides. |
| Compounds | This type of substance can be chemically broken down in a lab into component elements |
| Nonmetals | These substances can be solids, liquids, or gasses at room temperature without conducting electricity. |
| Ti can be classified as this type of matter. | Element - only made of one type of atom |
| Series | Elements that are in the same row (Left to right) are part of this grouping. |
| Goggles | This cool eyewear is essential for all lab experiments |
| Helium and Methane (CH4) can both be classified as this type of matter | Pure substances |
| Substances to the left of the stair step and are malleable | Metals |
| Columns/groups | Elements with similar properties are found in this |
| Chemical Reactions | Elements and compounds can go through this type of reaction to create new compounds with chemical properties |
| Tossed salad is a classic type of mixture | Heterogeneous mixture |
| H2O (water) can be classified as this type of matter | Compounds - made up of two elements chemically combined |
