The halogen group is the MOST reactive nonmetal group.
The Halogens are the most reactive non-metals. However, their reactivity decreases as you go down the group. Most reactive Fluorine>Chlorine>Bromine>Iodine>Astatine Least reactive. However, Astatine is not fully characterised because it is radio-active, and consequently is not found in open(school) labs.
The Halogen Family is the most reactive group of nonmetals.
The most reactive nonmetals are the halogens in group 17 of the periodic table.
