Hint:In order to answer the number of valence electrons present in Fluorine, we must first know about the atomic number and electronic configuration of Fluorine. Fluorine is a chemical element which is represented by the chemical symbol ‘F’ and it will be having an atomic number of 9.

The electronic configuration of fluorine is given as $1{s^2}2{s^2}2{p^5}$ which can also be written as $[He]2{s^2}2{p^5}$. From the electronic configuration, we can say that the number of valence electrons present in the Fluorine is 7. Fluorine will be having an oxidation number of -1.
