Question

Examples of malleable metals are:
(A) Gold and lead
(B) Aluminium and copper
(C) Silver
(D) All of the above

Answer 1

Hint Metals and nonmetals can be distinguished on the basis of their physical and chemical properties. The properties like hardness, lustrous, malleable, ductile, sonorous and conductivity of metals and nonmetals..

Complete step by step answer:
- Metals have various properties.
- One of the properties of a metal which can be drawn into thin wires is called ductility. For example, copper, aluminium.
- The property of metal when things made by metals produce a ringing sound when struck hard. The metals produced ringing sounds said to be sonorous. This property of metals is known as sonority. For example, silver.
- When a metal surface is exposed to the dry or wet atmosphere, the destruction of metal surface starts at the metal surface, and the formation of metal oxides is known as corrosion of metal. For example, rusting of iron.
- The metals property which can be beaten into sheets when hammered. For example steel, aluminium, copper, silver, lead etc.
- So, from the above context, we can say that examples of malleable metals are gold, silver, aluminum, copper, lead.

Therefore, the answer to the question is option (D) All of the above.

Note: Nonmetals are not sonorous, non-malleable, non-ductile and poor conductors of heat and electricity. The examples of non-metals which exhibit these types of properties are sulphur, carbon, oxygen, phosphorus, etc.
