Identify the element in question, which is fluorine (F).
Determine the atomic number of fluorine, which is 9, meaning it has 9 electrons in total.
Recall that valence electrons are the electrons in the outermost shell (energy level) of an atom.
Write the electron configuration of fluorine: \$1s^2 2s^2 2p^5$.
Count the electrons in the outermost shell (the second shell), which includes the \$2s^2$ and \$2p^5$ electrons, totaling 7 valence electrons.
