How many valence electrons does the lewis structure for a chlorine atom show

7 valance electrons the Lewis structure for a chlorine atom show.

Explanation:

Lewis structure is used to keep track of the valance electrons of each atom and share them in bonding. Every valance electron is represented as a dot around the element to keep their count.  

Paired VE’s are shown as ‘:’ and unpaired as ‘.’ in the representation. A chlorine Cl atom has 17 electrons. & of them are valance electrons. Out of the seven six are paired electrons and one is unpaired.  

i think   the answer is c hope i'm right
