Helium gas is used to inflate blimps, scientific balloons and party balloons. It is used as an inert shield for arc welding, to pressurize the fuel tanks of liquid fueled rockets and in supersonic windtunnels.
An inert gas is a gas that has extremely low reactivity with other substances. The noble gases —helium, argon, neon, xenon, krypton, radon, and element Uuo —exist in their elemental form and are found in Group 18 of the periodic table. What are the Colours of noble gases?
