       The Halogens are non-metallic elements found in Group 17 of the 
       Periodic Table. All Halogens have 7 electrons in their outer shells, 
       giving them an oxidation number of -1. The members of the Halogen 
       family are highly reactive, toxic to humans, and go from gas to 
       liquid to solid at room temperature as you descend the group. The 
       word "halogen" means "salt former" or "salt maker". When Halogens 
       react with metals, they produce a wide range of salts. Halogens also 
       have a high electronegativity and electron affinity.
