The Noble Gases.
Some are but the most reactive are also non-metals.
The Noble Gases.
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.
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
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 Nobel gasses. Generally inert.
Nitrogen (N) is likely to be the least reactive among the nonmetals listed. It is a diatomic gas with a stable triple bond that makes it less reactive compared to phosphorus (P), sulfur (S), and oxygen (O) which are more readily reactive due to their lower bond strengths.
Helium is the least reactive element, to the point of being unreactive.
The most reactive nonmetals are the Halogens. They are located in the second to last row on the Periodic Table from the right.
unreactive nonmetals are called noble gases
It is not true; many metals are very reactive and several nonmetals are nonreactive.
