Halogens.
The most reactive nonmetals are the halogens in group 17 of the periodic table.
Sodium is by far the most reactive. It self ignites in air (it is stored in oil), reacts vigorously with water (releasing hydrogen) and reacts explosively in acids-even dilute. But the most reactive metal is Cesium and the most reactive non-metal is Flourine Cesium and H20 will explode...
Nitrogen and oxygen are gases, nonmetals.
Among the elements listed in the question, potassium, by a large margin, is most reactive.
The most reactive NON-METAL is Fluorine. It is found in group 7, period 1. It is the most reactive non-metal because there is a strong electrostatic force, as there are no shells of electrons shielding the force therefore strong force enables the nucleus to attract another electron so that the outer-electron shell is FULL and the atom can become stable. Fluorine is diatomic, (eg. exists in pairs), so the symbol for Fluorineis F2
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.
Metals: alkaline metals Nonmetals: halogens
The most reactive nonmetals are located in top most right section of the Periodic Table, excluding group 18 (has no reactivity).
one is florine
