Explain the physical properties of metals with suitable examples.

Following are the physical properties of the metal:-

a) Sonority: Most of the metals produce sounds when they are struck or dropped on the ground. This property of the metal is called sonority. E.g Bells in the temple is made up of metals so that they generate sound when they are struck.

b) Malleability: In general most of the metals can be drawn into fine sheets on applying pressure with the help of the hammer. This property is called Malleability. e.g Aluminum foil that we use in covering our food is made from aluminum by hammering it into the shape of thin sheets.

c) Ductility: Most of the metals can be hammered into the shape of thin wires. This property of metal is called ductility. e.g electrical wires are drawn from the metal by hammering into it.

d) Conductivity: Metals allow the heat and electricity to flow through them. This property of metal is called conductivity. e.g wires are made of copper so that electricity flows through them.

e) Lustrous: Generally metals have bright surface. Because of this reason, they are employed in making jewelry. e.g Gold, silver

f) Density: They have high density, as a result, they are hard in nature. For example, iron is very hard in nature and is used in making bridges etc so as to withstand the heavyweight.
