Noble gases are monoatomic in nature. Explain.

Explanation

### Step-by-Step Solution:

1. **Understanding Noble Gases**: Noble gases are a group of elements found in Group 18 of the periodic table, including helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

2. **Electronic Configuration**: The outermost electronic configuration of noble gases is Ns²Np⁶. This means that their outermost shell is completely filled with electrons. For example:
- Helium has 1s²
- Neon has 2s² 2p⁶
- Argon has 3s² 3p⁶
