It is in Group 7 on the Periodic Table which means it already has 7in its outer shell. The shell needs 8 to be complete so fluorine requires 1 more electron which it gains through ionic or covalent bonding.
Seven electrons are there in the outermost shell of Florine.
There are seven electrons in fluorine's outer (second) energy level.
Fluorine has 7 electrons in its outermost shell and so it only needs 1 more to fill it.

Chlorine has 17 electrons, distributed in the following way: 2 in first shell 8 in second shell 7 in third (outer) shell Therefore Chlorine has 7 electrons in its outer shell.
8 - called valence electrons. it doesn't matter what energy level or orbital shape. a "happy atom" has 8 valence electrons
16 ... if it's not ionized. A neutral atom would have 16 electrons, one negative charged electron for each positive charged proton. Now an atom does not have to be neutral, it can have more or less electrons, which is called an ion. 16 Protons would make this a Sulfur atom, which is going to try to aquire 2 more electrons to have a complete orbital shell.
The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.

Fluorine and Chlorine are in the 7th group. They have 7 electrons in outer shell.
7Fluorine has 7 electrons in the outer level.

A fluorine atom has seven unshared electrons in its outer most shell (valence shell).
Calcium has two electrons in the outer shell.
Vanadium has on the outer shell two electrons.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
8 electrons on the outer shell
7 electrons
Fluorine has 9 in total. 7 in the outermost shell
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
