Explanation:

The electron - dot symbol (Lewis dot symbol) uses dots to represent the valence electrons of an atom. Fluorine has an atomic number of 9. Its electron configuration is \(1s^{2}2s^{2}2p^{5}\). The valence shell is the second shell (\(n = 2\)), and the number of valence electrons is \(2 + 5=7\).
