Question

Among the following, the number of elements that do not show malleability is:
Zinc, Iron, Sulphur, Aluminum, Nickel, Chlorine, Iodine.

Answer 1

Hint: Malleability is the property in which the elements can be turned into thin sheets. This property is only shown by metals. Non-metals will not possess this property. Among the above elements, some are non-metals; those elements will not show malleability properties and will not be malleable.

Complete answer:
Malleability describes the property of a metal's ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped, and rolled into a very thin sheet without rupturing. A malleable fabric could be planate by a blow or rolling.
Malleability is commonly characterized by a material's ability to create a skinny sheet by blow or rolling. This property isn't seen in non-metals. Malleable metals will bend and twist into numerous shapes when affected by a hammer, whereas non-malleable metals might break apart into pieces.
Now, by the above information, we can say that the non-metals will not show the malleability property. And among the options given above only Sulphur, chlorine and iodine are non-metals thus they will not show malleability. Therefore the number of elements that do not show malleability is three and these elements are Sulphur, Chlorine and Iodine.

Note:
Malleability in metals is very important in the appliance and automotive industries. This property helps to construct refrigerators, microwaves and stoves, and also helps to construct flat and curved metal objects. Gold and silver are highly malleable. Non-malleable metals may break apart when struck by a hammer. Malleable metals usually bend and twist in various shapes.
