Recall that the atomic number of an element represents the number of protons in the nucleus of an atom of that element.
For a neutral atom, the number of electrons is equal to the number of protons to balance the positive charge of the nucleus.
Given that the atomic number of fluorine (F) is 9, this means it has 9 protons.
Since the atom is neutral, it must also have 9 electrons to balance the charge.
Therefore, the number of electrons in a neutral fluorine atom is equal to its atomic number, which is 9.
