Why helium and neon do not form compounds with fluorine?

Explanation

To understand why helium and neon do not form compounds with fluorine, we can break down the explanation into several key points:

### Step-by-Step Solution:

1. **Atomic Structure of Helium and Neon**:
- Helium has the electron configuration of 1s², and neon has the electron configuration of 1s² 2s² 2p⁶. Both elements have fully filled outer electron shells.

2. **High Ionization Energy**:
