What are physical properties of metals

Physical properties of metal

• Metals are solid except mercury that is found in liquid state at room temperature.
• They are hard and tough except sodium and potassium that can be cut with a knife.
• They are lustrous i.e. they shine in light because metals possess free electrons that vibrates on getting in contact with light.
• They have high melting points except caesium and gallium have very low melting point.
• They are good conductors of heat and electricity. The best conductors of electricity are silver and copper whereas lead and mercury are comparatively poor conductors.
• They have high density except alkali metals like lithium, sodium and potassium.
• They are malleablee. they can be beaten into thin sheets. For instance, the aluminium foil we use to pack food is manufactured by beating the aluminium metal into thin sheets. This a characteristic property of metal.
• They are ductilee. they can be drawn into wires. For instance. We all are familiar with copper and aluminium wires. It is due to their characteristic property of ductility that these metals can be drawn into wires.
• They are sonorouse. they produce a ringing sound when struck against a hard object. For instance, your school bells are made of metal that produces a ringing sound after the period is over when struck hard by a hammer.
