the halogens decrease in reactivity as you move down the group, so i guess that the least reactive would be Astatine. Hope this helps =)

Which of the two halogens shown is more reactive?
The most reactive halogen, and one of the most reactive of all the elements, is fluorine. Reactivity in the halogen family continues in order from most reactive to least reactive with chlorine, bromine, iodine, and astatine.
Which group on the periodic table contains the most reactive nonmetals?
The Halogen Family is the most reactive group of nonmetals.
Which nonmetals ae most chemically reactive?
The halogens, which is group 17, are the most reactive non-metals. Oxygen is pretty reactive too, even though it's not a halogen.
Does group 7A of the periodic tables contain the least reactive nonmetals?
The halogen group is the MOST reactive nonmetal group.
Do less reactive halogens displace more reactive ones?
No. More reactive halogens will replace less reactive ones in a compound. This is because a more reactive halogen is more stable in a compound relative to a less reactive one, while a less reactive halogen is relatively more stable in its elemental form.
Which is the third most reactive halogen?
Bromine (Br2) is the third most reactive halogen.
Which halogen is most reactive?
Fluorine
