The Noble Gases. The elements of Group VIII of the Periodic Table are gases which have closed shells and are unreactive chemically. Helium, neon, argon and krypton are used in gas discharge decorative ligthing, called neon lights.Argon is used to fill incandescent light bulbs to inhibit the evaporation of the tungsten filaments and increase bulb life. Xenon is used in electronic flash tubes for cameras and other flash tubes.elium, neon, argon and krypton are used in gas discharge decorative ligthing, called neon lights.

Argon provides an inert atmosphere in which welded metals will not oxidise. Appearance. Argon is a colourless, odourless gas that is totally inert to other substances. Uses. Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.
