Question

which of the following materials is known for its ductility?
a copper
b sulfur
c carbon
d silicon

Explanation:

Ductility is the ability of a material to be drawn into wires. Metals generally have high ductility, while non - metals like sulfur, carbon, and silicon (a metalloid with more non - metal - like properties in terms of ductility) are brittle. Copper is a metal and is known for its ductility. Sulfur is a non - metal, brittle. Carbon (in forms like graphite has some ductility but overall carbon as a non - metal in general context here is brittle), and silicon is a metalloid with low ductility. So among the options, copper is the material known for ductility.

Answer:

a. Copper
