Which is the most ductile metal known?
(1) Silver
(2) Platinum
(3) Gold
(4) Copper
Answer: (3)
Explanation:
Metals are shiny, opaque elements that transfer heat and electricity well. Most metals are malleable and ductile, and they have a higher density than the other elements.
The physical property of the metal is ductility, which indicates that if we pull it, it will stretch rather than break. The ability of a material to undergo significant plastic deformation under tensile stress before rapture is referred to as its ductile characteristics. Nickel, copper, steel, and other ductile materials are examples.
Ductility is a key consideration in engineering and production, determining a material’s suitability for a certain application as well as its ability to withstand mechanical overload.
Copper and other ductile metals may be pulled into long, thin wires without breaking. Copper has long been known as a good conductor of electricity, but it can also conduct just about everything. When tensile stress is applied to metals with low ductilities, such as bismuth, they will break.
The most ductile metal is gold. One gramme of gold may produce a wire with a length of around 2 kilometres. Metals may be shaped into various shapes depending on our demands due to their malleability and ductility.
Therefore, among the given metals, gold is the most ductile metal.
