Question

Identify the odd term
Ductility, brittleness, sonority, malleability

Answer 1

The correct answer is Brittleness.

The brittleness is considered as the lack of ductility and for the brittle metal, you need not to perform any plastic deformation.

However, the elastic stage will be followed by means of instant fracture.

Some of the examples of the brittle materials are gray cast iron, stone, ceramics, concrete, glass etc.

Answer 2

Brittleness

Explanation:

• Brittleness is the odd term among the given options as it is the characteristic property of a non-metal While the other three are the defining physical properties of metals.
• Brittleness is described as the property of being liable to break or snap easily under pressure or stress.
• For Example; A diamond is hard but brittle(breakable) as it is a non-metal.
• Metals, on the other hand, are ductile and malleable. They are also sonorous as they produce a particular sound when hit or struck with a rigid object.
• Thus, the correct answer is brittleness.
