No, Group 8A (Noble Gases) are the least reactive nonmetals because they have a full outer shell of electrons and do not readily form chemical bonds. Group 7A (Halogens) are more reactive in comparison.
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 halogens are the most reactive nonmetals. They belong to Group 17 on the periodic table.

Group 7. Fluorine, which belongs to group 7, is the most reactive element.
group 17 or halogens
The group on the periodic table that contains the most reactive nonmetals is Group 17, also known as the halogens. This group includes elements like fluorine, chlorine, bromine, and iodine, which have a strong tendency to gain an electron to achieve a stable electron configuration.
Beryllium is the least reactive in the group 2.
