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?
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.
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.
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.

in a normal F- ion there are 10 electrons total (but 8 in the outer energy level)
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
Fluorine has 7 valence shell electrons. If it has a formal charge of (-1) that means that it has 8 non bonding electrons. Its atomic number is 9 therefore the fluorine anion (F-1) has 8 electrons and 9 protons.
flurine has atomic no. 9 so its electronic configaration is 2,7. Its valance shell has 7 electrons
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Krypton has 8 valence electrons.

The total number of electrons in a neutral fluorine atom is 9, which is the atomic number of fluorine.

Fluorine is the element with atomic weight closest to 19 amu. Fluorine has an atomic number of 9, so an electrically neutral fluorine atom would have 9 electrons.
