Contrast metals and nonmetals by describing three ways in which they are different. Then, identify one example of a metal and one example of a nonmetal

Metals = good conductors of heat and electricity, malleable, lustrous, (some examples of metals are copper, aluminum, and iron) Non-metals = poor conductors, brittle, dull (some examples of non-metals are carbon, sulfur, and chlorine)
