1. Type of metal

2. Purity of metal

3. Nature of metal surface

4. All the above

Metals can be easily identified by comparing their physical properties. When metals are in their pure state, they have a shining surface. It is called metallic lustre. Metals like gold and silver are malleable means they can be beaten into thin sheets. It is called malleability. Some metals are generally hard and their hardness varies from metal to metal.

Answer: The work function of a metal depends on the type of metal, nature of the metal surface, and purity of the metal.

When metals strike a hard surface they produce a sound that is known as sonorous. They are good conductors of heat and possess high melting points. So, it can be said that metals are generally hard, lustrous, malleable, ductile, sonorous, and good conductors of heat and electricity.

More about Metals

The crucial information related to metals is given below:

  • Potassium and Sodium are soft and can be cut with a knife.

  • The only metal which is found in the liquid state at room temperature is Mercury.

  • Sodium is a very reactive metal and it reacts vigorously with water and oxygen hence it is stored in kerosene.

  • When metals react with acids it produce hydrogen gas and burn with a ‘pop’ sound.
