Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal.
(i) Metals in their pure state, have a shining surface. This property is called metallic lustre. Metals are generally hard. The hardness varies from metal to metal.
(ii) Metals can be beaten into thin sheets. This property is called malleability.
(iii) Ductility the ability of metals to be drawn into thin wires. Gold is the most ductile metal.
