| Conductivity | ability to conduct electrical current or thermal energy |
| Density | the amount of matter that will fit into a given amount of space |
| Ductility | ability to be stretched into a wire without breaking |
| Hardess | ability of a mineral to resist scratching |
| Luster | how the surface of a mineral appears when it reflects light (e.g., shiny or dull) |
| Malleability | ability to be formed or shaped under pressure (e.g., metals hammered or rolled into thin sheets) |
| Mass | the amount of matter in something |
| Metalloids | substances that exhibit some properties of metals and nonmetals |
| Metals | substances that have the physical properties of luster, conductivity, and malleability; may appear in all three states of matter |
| Nonmetals | substances that have the physical properties of being dull, insulators, and brittle; may appear in all three states of matter |
| Streak | the color of a mineral seen when rubbed on a streak plate |
| Volume | the amount of space that a substance or object occupies |
