Question

Which is the most ductile metal known?
$
  (a){\text{ Silver}} \\
  {\text{(b) Platinum}} \\
  {\text{(c) Gold}} \\
  {\text{(d) Copper}} \\
 $

Answer 1

Hint – In this question think of the concept that amongst the given questions is best framed into thin wires and is able to be deformed without losing its toughness.

Complete step-by-step answer:
Ductility of a metal is the property of a metal to convert the metal into thin wires.
As we know that the most ductile metal till now known is gold.
And the most malleable metal till now is gold.
So this is the required answer.
Hence option (C) is the correct answer.

Additional information
Metals are generally found to have strong metallic bonding so as the temperature increases their metallic bonding tends to lose this boost up the property of metal to be more ductile. Generally it is found that the ductility increases with increasing in temperature, that is it has an direct relationship. When temperature decreases the property of ductility rather changes to brittleness . There are several ways to increase the ductility of a metal that is by decreasing the percentage tension steel.

Note – Metals are described as malleable that can be easily beaten into thin sheets. Metals show properties of ductility and malleability because of the ability of atoms to roll over each other into new positions without breaking the metallic bond that is present in between them. So in other terms the greater is the flexibility of this metallic bond the more the changes of metal to be ductile and malleable.
