Question

Most ductile metal among the following is:
A. Zinc
B. Nickel
C. Copper
D. Silver

Answer 1

Hint:The metals show some physical properties like malleability, ductility, conductivity. The ductility is the property shown by metals due to which they can be drawn into thin wires. The property is shown by the metals possessing low hardness.

Complete step by step answer:
Metals are elements which are obtained naturally from the surface of earth. Metals are lustrous and shiny in nature. Metals are a good conductor of heat and electricity. They have the physical property of malleability and ductility.
The malleability is defined as the property of metal in which they are beaten into thin flat sheets. Examples: Aluminium sheets are utilized for the manufacturing of Aircraft as they are light in weight. The other metal sheets are used in automobiles industries and making utensils. As the metals can be beaten into sheets they are considered as malleable.
The ductility is defined as the property in which the metals are stretched into wires. Because of ductility the metals are transferred into thin wires. Examples of copper are used in making cable wires. The ductility is a permanent strain which is accompanied by the fracture in a tension test. As the metal can be drawn into these wires, they are considered as ductile.
Among the given metals zinc, nickel, copper, silver, the metal silver is the most ductile in nature. It can be easily converted into these wires.
Therefore, the correct option is D.

Note:
The ductility of the metals is affected by the temperature. The ductility of the metal decreases on increasing the temperature as the metals get weaker on increasing the temperature.
