| Metals | A solid substance that is a good conductor of heat and electricity. Can be formed into many shapes. |
| Metalloid | "Middle elements" - conduct heat and electricity better than nonmetals, but not as well as metals. Easier to shape than nonmetals, but not as easy as metals. Solid at room temperature. |
| Nonmetals | A poor conductor of heat and electricity. Not easily formed into shapes. |
