(i) Non-metals are non-ductile and non-malleable.

(ii) Non-metals are non-sonorous.

(iii) Non-metals are poor conductors of heat and electricity.

Iron displaces copper from copper sulphate solution to form a light green solution of ferrous sulphate.

Electric wires are made of copper because it is good conductor of electricity and cheper than other metallic wire.

(i) Metals can be hammered to make sheets so they are malleable.

(ii) Metals can be drawned into very thin wires, that means metals are ductile.

(iii) Metals are good conductors of heat and electricity.

The property of metals by which they can be beaten into thin sheets is known as malleability. Silver and gold are the most malleable metals.

Non-metals are neither malleable nor ductile.
