Metals | A solid substance that is a good conductor of heat and electricity. Can be formed into many shapes.
Metalloid | "Middle elements" - conducts 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.
Non-metals | A poor conductor of heat and electricity. Not easily formed into shapes.
