In the Periodic Table we will find 5 halogens, in the coloumn one from the far right (which is the noble gas coloumn). The halogens are, in ascending Atomic Mass: flourine, chlorine, bromine, iodine, and astatine. As far as percentages go we keep coming up with new synthetic elements (thus the percentage would be dynamic), but last time I checked my table we had somewhere around 112. So.. (5/112) = approximately 4.46%.
