Are noble gases flammable?

Noble gases are indeed non-flammable due to their inherent chemical properties. They are characterized by having a full outer shell of electrons, which makes them stable and unreactive under normal conditions. This stability means that noble gases do not readily form bonds with other elements or compounds, including those that are flammable.

Unlike many other gases, noble gases—such as helium, neon, argon, krypton, xenon, and radon—do not support combustion. For a substance to be flammable, it must react with oxygen and produce heat and light during combustion. The lack of reactivity in noble gases means they do not participate in such reactions, confirming their non-flammable nature.

In contrast, other gases can be flammable if they can combine with oxygen and release energy; however, noble gases do not share this property, thus reinforcing the understanding that they are safe from catching fire or supporting flames.
