Question

Can fluorine exhibit positive oxidation states?

Answer 1

1. Fluorine shows only the −1 oxidation state in all its compounds.
2. It is the most electronegative element and strongly attracts electrons, always gaining rather than losing them.
3. Fluorine has no vacant orbitals in its valence shell and cannot excite electrons to higher orbitals.
4. Thus, it cannot form bonds that result in positive oxidation states.
5. Other halogens have vacant d-orbitals and can show positive oxidation states, but fluorine cannot.

Hence, fluorine never exhibits positive oxidation states, always remaining at −1.
