Question

The property of metals by which they can be beaten into thin sheets is called:
A. malleability
B. ductility
C. conduction
D. expansion

Answer 1

Hint: All the options here are the metallic characters. The changing shape into sheets under pressure is known as the malleable nature of the element. The non-malleable elements break under pressure.

Complete step by step answer:
- The metallic properties include the property of being able to be hammered resulting in the formation of thin sheet structures. This is because every time the force is applied to the metals it can spread out into thin structures. Among all the given options which are specific for the characters of metallic elements, malleability defines the property of formation of thin sheets from metals. The correct answer is option “A” .
- Therefore, by hammering or pressing the metal structure, the formation of sheets is possible. But even due to the introduction of pressure there is no chance of breakage of the specific metal structure. Thus, even with that amount of pressure, the metal changes shape only. Using the highest level of pressure of hammering the metal structures are changed to sheets.
- Ductility of a metallic element defines that the element can be used for the formation wires. The conduction is another character of metals which proves that metals can conduct electricity or heat faster due to the presence of excess electrons in their shell. The presence of that electron facilitates the process of conduction. The metals have the ability to expand under increased heat change.

Note: Gold is the most malleable element in the world. Hence it is perfect to be used for the production of ornaments because it can be converted to different structures and shapes. Malleability is observed in all metals but the level of malleability differs among them.
