Which of the following statements is/are NOT correct?

I. The property of metals by which they can be beaten into thin sheets is called malleability.

II. The property of metal by which it can be drawn into wires is called ductility.

Neither I nor II

The correct answer is option 2. Both I and II.

Let us go through each statement:

Statement I: "The property of metals by which they can be beaten into thin sheets is called malleability."

This statement is correct. Malleability is a property of metals that allows them to be hammered, rolled, or pressed into thin sheets without breaking. This characteristic arises from the metallic bonding within the metal lattice, which allows atoms to slide past each other when force is applied, allowing the metal to change shape without rupturing.

Statement II: "The property of metal by which it can be drawn into wires is called ductility."

This statement is also correct. Ductility is a property of metals that allows them to be stretched into thin wires without breaking. Similar to malleability, ductility is a result of the metallic bonding within the metal lattice, which enables the metal to deform plastically under tensile stress, allowing it to be drawn into a wire form.

Therefore, both statements accurately describe the properties of metals, and the correct answer is option 2: "Both I and II."
