Write physical properties of metals?

Physical properties of Metals:

(i) State: Metals are amorphous solids. Only mercury is an exception which is not a solid. It is a liquid. They retain their shapes under normal conditions.

(ii) Hardness: Metals are very hard. Sodium is an exception which is not very hard. It can be cut into pieces easily. Hardness varies from metal to metal.

(iii) Metallic lustre: Most of the metals have a shining surface. They have a metallic lustre. Their shining can be intensified by polishing.

(iv) Malleability: Metals can be beaten into sheets. For example aluminium is beaten into sheet for different purpose.

(v) Ductility: Metals are ductile because they can be drawn into wires of desired diameter. metals like copper and aluminium used in electrical wires.

(vi) Conductivity. Metals are good conductors of heat and electricity.

(vii) Sonorousity. Metals are sonorous. They produce a ringing sound when struck.

(viii) High melting point. Metals have very high melting point. gallium is an exception which melt on your hand.

(ix) Tensile strength. Metals have a tensile strength. They can be stretched up to some degree without fracturing.
