Why fluorine ghas only one oxidation state?

Explanation

**Step-by-Step Solution:**

1. **Identify the Element**: Fluorine is a halogen and belongs to Group 17 of the periodic table. It has an atomic number of 9.

2. **Electron Configuration**: The electron configuration of fluorine is 1s² 2s² 2p⁵. This means it has 2 electrons in the first shell and 7 electrons in the second shell (2 in the s subshell and 5 in the p subshell).

3. **Valence Electrons**: Fluorine has 7 valence electrons (2 from the s subshell and 5 from the p subshell). To achieve a stable octet configuration, fluorine needs to gain 1 electron.
