Why are non-metals brittle ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Non-Metals**: Non-metals are elements that generally lack the characteristics of metals. They have different physical and chemical properties compared to metals.

2. **Bonding in Non-Metals**: The primary reason for the brittleness of non-metals is the nature of their bonding. Non-metals typically form covalent bonds, where atoms share electrons. However, these bonds are not as strong as the metallic bonds found in metals.

3. **Weak Intermolecular Forces**: In non-metals, the forces that hold the particles together (intermolecular forces) are relatively weak. This means that when stress is applied (like hammering), these forces cannot withstand the pressure, leading to the material breaking or shattering.
