In an atom of Cl, there are 7 valence electrons. If you look at a Chemistry Reference table (2002 edition) pages 8 and 9, (visit the link below), you can see that underneath Cl there are the numbers 2-8-7. The last number is the number of valence electrons. This is found for any element on the Period table.
