it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
1 electron is required to fill fluorine . F has 7 valence electrons.
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
nine
Fluorine's atomic number is 9. Thus, fluorine has 9 protons and 9 electrons. As with every atom, all 9 of fluorine's electrons are found in the electron cloud.
If the ion is the most common anion of fluorine, a fluoride ion, it contains 10 electrons.
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
The total number of electrons in a neutral fluorine atom is 9, which is the atomic number of fluorine.

In a neutral atom of fluorine, there are 9 electrons. The number of neutrons varies with an isotope's mass number.
The fluorine isotope differs from the fluorine ion because the fluorine isotope has a different number of neutrons from normal, while the ion has a different number of electrons. An isotope will have the same number of electrons as its atomic number (the number of protons), while the ion will add (more common in the case of fluorine) or subtract (very rare in the case of fluorine) electrons to the atom. The only thing they are similar in is the number of protons they have, which are the same.
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.

Fluorine has the atomic number of 9. This means it has 9 protons in the nuclei of its atoms. So, a neutral fluorine atom would also have 9 electrons.
in a normal F- ion there are 10 electrons total (but 8 in the outer energy level)
7 valence electrons
