in a normal F- ion there are 10 electrons total (but 8 in the outer energy level)
8 valance electrons in valance shell means that atom is stable.
the number of electrons in a valence shell is 8
Fluorine and Chlorine are in the 7th group. They have 7 electrons in outer shell.
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.

It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.
flurine has atomic no. 9 so its electronic configaration is 2,7. Its valance shell has 7 electrons

A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
Valance electrons
8 valance electrons in valance shell means that atom is stable.
There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.
the number of electrons in a valence shell is 8
Fluorine and Chlorine are in the 7th group. They have 7 electrons in outer shell.
