Chlorine has seven valence electrons.
The electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p5.
These seven valance electrons do NOT readily react, because they are 'tightly' held to the nucleus. However, chlorine has strong electron affinity; Electronegativity; this means it will attract one electron into its valance shell , to complete the octet of eight electrons in the valance shell.
When this 'extra' electron combines into to valance shell , the electron configuration is 1s2, 2s2, 2p6, 3s2, 3p6. , and the chlorine atom is now a 'CHLORIDE ANION' of charge '-1' , (symbolised by Cl^(-)).
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.
Chlorine has 7 valence electrons.
The electronic configuration of chlorine is 2,8,7 So there are 7 electrons in the valence shell (or highest energy level).
You would need 1 more electron to make a Chlorine atom stable with 7 valence electrons. This additional electron would allow Chlorine to achieve a full valence shell of 8 electrons, following the octet rule.
3s and 3p, remember Cl has 7 valance electron. 3s^2 and 3p^5
