Which of the following materials is brittle ? 1. wood 2. metal 3. ceramic 4. plastic

Option (3) is the correct answer.

Explanation:

In metals there is metallic bonding and due to this atoms tend to slide past each other easily.

Whereas in ceramic, there are combined ionic and covalent bonding which tends to resist the movement of atoms. As a result, ceramic is brittle in nature.

For example, a ceramic pot easily breaks when it falls from a table to the ground.

Thus, we can conclude that out of the given options, ceramic materials is brittle.
