Question

Which of the following can be drawn into thin wires?
(A) $Br$
(B) $Al$
(C) $Cl$
(D) $At$

Answer 1

The criteria for an element to be drawn into thin wires , the element should be ductile . We know that metals are malleable and ductile . Hence , we have to find the element which is a metal .

Complete step by step answer:
Elements which donate electrons are known as metals while those which accept electrons are non-metals.
Metals donate electrons to complete their octet and attain noble gas configuration.
They usually have one, two or three electrons in their valence shell so it is easier for them to donate electrons rather than accepting more electrons.
Among the given elements , bromine belongs to group 17 and is a non - metal . Aluminium is a metal and belongs to group 13 . Chlorine belongs to group 17 and is a non - metal . Astatine is also a non - metal which belongs to group 17 .
So , among the given elements aluminium is a metal which can be hammered into thin wires .
Metals can be drawn into thin wires. Aluminium is a metal in which the given elements have ductility. A material that can be stretched thin when tensile stress is applied is called to be ductile and the property is known as ductility . The types of metal commonly used, because of their high level of ductility, include gold, silver, copper, and aluminium.

So, the correct answer is Option B.

Note:
Aluminium is lightweight, durable, malleable and corrosion-resistant. This metal is widely used in the aerospace, transportation and construction industries because of its versatility .
