Oxidation state:

• "The oxidation state of an element in a compound ascertained according to a set of rules formulated on the basis that electron pair in a covalent bond belongs entirely to a more electronegative element."

Oxidation state of Flourine:

• Fluorine is a chemical element having an atomic number $9$ and an atomic symbol $\mathrm{F}$.
• Fluorine as well as other halogens have an oxidation number $–1$ when they exist as halide ions in their compounds.
• Thus, the most common oxidation state of Fluorine is $–1$.
