how are noble gases used?
22705
The noble gases are used to form inert atmospheres, typically for arc welding, to protect specimens, and to deter chemical reactions. The elements are used in lamps, such as neon lights and krypton headlamps, and in lasers. Helium is used in balloons, for deep-sea diving air tanks, and to cool superconducting magnets.

Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).

All noble gases are non metals. All the noble gases except radon occur in the atmosphere. All these are gases. They are chemically unreactive.

The science. The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don't react with anything. For this reason they are also known as inert gases.

Now, why do Noble gases glow exactly? Well scientists believe that the Noble gases glow when a chemical current is passed through them because the outer energy levels are full they give out another energy level which results in the "neon" glow.

How Noble Gases Form Compounds. Helium, neon, argon, krypton, xenon, radon have completed valence electron shells, so they are highly stable. The filled inner electron shells tend to provide a sort of electrical shielding, making it possible to ionize the outer electrons.

Argon. A noble gas, argon is inert and colorless until an electric current excites it to a rich sky-blue glow. As one of the least expensive noble gases, dense argon is often used as a shield gas to protect against oxidation. Scroll down to see examples of Argon.

A noble gas is different from other elements because its highest electron energy level is completely filled. The examples of noble gases are helium, neon, Argon , krypton,Xenon , radon.

Noble gases like helium (He), Neon (Ne), and Argon (Ar) are chemically inert and are present in atmosphere in extremely low concentrations. Thus owing to their similar inert behaviour and similar electronic configuration, they are justified to be placed in a separate group.
73108
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

The group 0 elements, the noble gases, are all unreactive non-metal gases. They show trends in their physical properties. Their uses depend on their inertness, low density and non-flammability.
590875
Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment. ... This chemical series contains helium, neon, argon, krypton, xenon, and radon.

Argon is used in light bulbs. Helium is used in balloons and to cool things. Xenon is used in headlights for new cars. Because of their chemical properties, these gases are also used in the laboratory to help stabilize reactions that would usually proceed too quickly.

They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.
468485
The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons. Although noble gases do not normally react with other elements to form compounds, there are some exceptions.
909958
The noble gases are in Group 18 (8A). They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. ... Because this configuration is extremely stable as well as symmetrical, the noble gases are very unreactive.

Noble gases are monoatomic, which means they exist as single atoms. This is because of their electronic stability. Unlike most common gases that exist as diatomic molecules like O2, N2, and Cl2, the noble gases exist as single atoms like He, Ne, Ar, i.e. they are monatomic molecules.
