11 electrons makes the third energy level complete. One
It needs only 1 more electron since it already has 7 valence electrons.
Bromine requires 1 electron to become Krypton and a thus a full valence electron

One. (Apex)
The element chlorine has seven electrons in its valence shell.
1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
Third Shell
The electronic configuration of chlorine is 2,8,7 So there are 7 electrons in the valence shell (or highest energy level).
Chlorine is extremely electronegative and will steal electrons from the valence shell of sodium. When chlorine steals the electron, both sodium and chlorine have full valence shells.
The element chlorine has seven electrons in its valence shell.
Chlorine has 7 valence electrons in the 3rd electron shell. Chlroine is in the third row of the periodic chart, so its 3rd shell is the valence shell, and it is in the next to last column, 7A, so it has 7 electrons in that 3rd shell.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.

Chlorine has 7 electrons in the outermost shell. It is in the 17th group. It has 7 valence electrons.
Chlorine has 7 electrons in the outermost shell. It is in the 17th group. It has 7 valence electrons.
In any atom, the valence electrons are located in the outermost shell. Chlorine has 7 valence electrons.

One.
The element chlorine has seven electrons in its valence shell.
17 electrons total - 7 of which are in the outer shell.
I reacts in order to get a filled valence shell of electrons.
