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.
A chlorine atom has 7 valence electrons as do the other halogens.
There are 7 valence electrons in chlorine.
An uncharged Chlorine atom has 7 valence electrons (3s2 3p5). If it accepts 1 additional electron to become a -1 ion, then it will have a full valence shell of 8 electrons.
7 valence electrons.

Chlorine has 7 electrons in the outermost shell. It is in the 17th group. It has 7 valence electrons.
2 valence electrons for calcium and 7 for chlorine.

Chlorine has 7 electrons in the outermost shell. It is in the 17th group. It has 7 valence electrons.
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.
2 valence electrons for calcium and 7 for chlorine.
