Chlorine is a yellowish-green, dense gas that has a very sharp smell.

This is chlorine's atomic structure. The P meaning number of protons, and N meaning the number of neutrons. The little minus' s are electrons and you know how many to put in the paths because it is the same number of protons. The first path holds 2 electrons, 2nd and 3rd paths hold 8 and the 4th path holds 18 electrons.
