Question

1. Of these, the most ductile metal is
(a) aluminium (AI)
(b) gold (Au)
(c) copper (Cu)
(d) zinc (zn)​

Answer 1

Answer:

here's your answer

b).....

Answer 2

Answer:

(b) gold (Au).

Metals with high ductility—such as copper—can be drawn into long, thin wires without breaking. Copper historically has served as an excellent conductor of electricity, but it can conduct just about anything. Metals with low ductilities, such as bismuth, will rupture when they're put under tensile stress.

Ductile metals can be used in more than just conductive wiring. Gold, platinum, and silver often are drawn into long strands for use in jewelry, for example. Gold and platinum are generally considered to be among the most ductile metals. According to the American Museum of Natural History, gold can be stretched to a width of only 5 microns or five-millionths of a meter thick. One ounce of gold could be drawn to a length of 50 miles.

Hence, the correct option is B
