$\tt\blue {Physical \: properties \: of \: metals - }$

• State - All metals are solid at room temperature. ( Only mercury is a metal in liquid form).

• Colour - Metals usually have silver or grey colour.

• Metallic Lustre - Metals in the pure state generally shine and can be polished .

The shine on the the metals are known as metallic Lustre.

• Hardness - Metals are generally hard like iron except some which are soft such as potassium and sodium.

• Ductility - Metals have the property of ductility , means that they can drawn into wires.

✴Gold and Silver are the best ductile metals.

• Density - Metals have high density. ( Exception - Sodium and Potassium , they are so light that they can even float on water.)

• Malleability - Metals can be beaten into thin sheets with hammer without breaking.

• Sonority - Metals are generally sonorous means they make a singing sound when we strike them.

• Conductivity - All metals conduct heat & electricity.

✴Silver is the best conductor of electricity.

• Melting & Boiling point - Metals have generally high melting points. ( Exception - Sodium and Potassium)
