|Luster||Metals reflects light from their surface and can be polished for example in gold, silver and copper.||Nonmetals does not reflect light.||They are not lustrous.|
|Malleability||Metals can withstand hammering and can be shaped into thin sheets such as foils.||Nonmetals are non-malleable.||Metalloids are not malleable.|
|Ductility||Metals can be inserted into cables.||Nonmetals are not ductile.||Metalloids are not ductile.|
|Thermal conductivity||Metals are good conductors of heat because they have free electrons.||Nonmetals are poor conductors of heat.||Metalloids are semiconductors of heat.|
|Electrical conductivity||Metals such as silver and copper are great conductors of electricity.||Nonmetals are poor conductors of electricity.||Metalloids are semiconductors of electricity.|
|State||Metals are room-temperature solids except for mercury and gallium.||Most of those non-metals occur at room temperature in two of the three states of matter.||Metalloids are solid at room temperature.|
