Metals: Metals are lustrous, sonorous, ductile, and are good conductor of heat and electricity.

Non-metals: Non-metals are no-lustrous, non-sonorous, non-ductile, and are bad conductor of heat and electricity.

Physical Properties

PropertyMetalNon-metalMalleabilityMetals are malleable, i.e. they can be beaten into thin sheets.Non-metals are not malleable.ConductivityMetals are good conductors of heat and electricity.Non-metals are bad conductors of heat and electricity. (exception: graphite)DuctilityMetals are ductile, i.e. they can be drawn into thin wires.Non-metals are not ductile.SonorousMetals are sonorous, i.e. they produce a typical metallic sound when hit with something.Non-metals are not sonorous.LustrousMetals have metallic shine; called lustre.Non-metals are usually dull. (exceptions: diamond and graphite)Physical StateMost of the non-metals are available as solid at room temperature; except mercury. Sodium and potassium are so soft that they can be cut with knife.Non-metals are available in all the three states of matter.
