Matter
| Question | Answer |
|---|---|
| Anything that has mass and takes up space | Matter |
| The amount of matter in something | Mass |
| Firm and stable in shape; | Solid |
| Having a consistency like that of water or oil, i.e., flowing freely but of constant volume. | Liquid |
| An airlike fluid substance which expands freely to fill any space available, irrespective of its quantity. | Gas |
| The amount of space something occupies | Volume |
| A property that can be observed without changing the identity of the substance. | Physical Property |
| A property that can 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 plus the number of neutrons in an atom | Atomic Mass |
| Center of the atom that has the protons and neutrons (heaviest part of the atom) | Nucleus |
| Positive subatomic particle in the nucleus | Proton |
| Neutral subatomic particle in the nucleus | Neutron |
| Negative subatomic particle that is around the outside of the nucleus | Electron |
| Ability to be flattened into a sheet; bendable | Malleability |
| Ability to be stretched into a wire | Ductility |
| Ability to react with another substance | Reactivity |
| Horizontal rows on periodic table | Period |
| Vertical columns on periodic table | Groups |
| Temperature where solid turns to liquid | Melting Point |
| Temperature where liquid turns to 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 |
