| Question | Answer |
|---|---|
| Anything that has mass and takes up space. | Matter |
| The amount of matter in something | Mass |
| The amount of space something occupies | volume |
| Usually hard holds its shape | Solid |
| Does not hold it's shape, particles have more freedom to move than solids, but not a lot. | Liquids |
| Particles are really spread out bounce around constantly. | Gases |
| A property that can be observed without changing the identity of the substance | Physical property |
| a property that can be only be observed by changing the identity of the substance. | Chemical Property |
| Smallest unit of matter | Atom |
| Number of protons in an atom of a given element | Atomic Number |
| Number of protons + the number of neutrons in an atom | Atomic Mass |
| Center of an atom that contains protons and neutrons | Nucleus |
| Positive subatomic particle in an atom | Protons |
| Neutral subatomic particle in an atom | Neutron |
| Negative subatomic particle that is around the outside of the nucleus | Electron |
| Ability to be flatted. | Malleability |
| Ability to be stretched into a wire | Ductility |
| Ability to react with another substance | Reactivity |
| Horizontal rows on a periodic table | Period |
| Vertical columns on a periodic table | Groups |
| Temperature where solid turns into liquid | Melting point |
| Temperature where liquid turns into gas | Boiling point |
| Shiny, good conductors, malleable, ductility | metal |
| Like both metal and non-metal, shiny, malleable, semi-conductors | Metalloid |
| poor conductors, mostly gases, dull | Non-metal |
| The amount of mass per unit of volume | Density |
