First of all, all halogens are non-metals. Secondly, the most reactive is fluorine, which reacts to nearly everything, hence it is rare. After fluorine comes chlorine, then bromine and iodine.
all the metals are reactive but the most reative metal is iron.
Fluorine is sometimes called the hungry wolf of the periodic table because it is the most reactive element.
I'd have to go with fluorine.
Both thermal conductivity and electrical conductivity tend to be higher in metals than in most other materials.
Well, nonmetals are opaque and brittle. They are also bad conductors of heat and electricity.
halogenes/non metals
halogenes
The most reactive nonmetals are the halogens in group 17 of the periodic table.
The most reactive nonmetals are the Halogens. They are located in the second to last row on the Periodic Table from the right.
The Halogen Family is the most reactive group of nonmetals.
The most reactive nonmetals are in group 17 (halogens). The most reactive metals are in group 1 (alkali metals).

halogens.
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.
Some are but the most reactive are also non-metals.
Fluroine is the most reactive non-metal.
