Give one example of an interstitial solid.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Interstitial Solids**: Interstitial solids are a type of solid solution where the solute atoms occupy the interstitial spaces (gaps) between the solvent atoms in a crystal lattice.

2. **Identifying the Components**: In an interstitial solid, there are two main components:
- The **solvent** (or host) atoms, which form the primary structure of the solid.
- The **solute** atoms, which fit into the gaps between the solvent atoms.
