Rare gases, are the 18 group of elements on the periodic table. There are six naturally occurring rare gases, namely helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radioactive radon (Rn). Rare gases are used in a variety of industries because of their chemical stability.

Uses of helium gas:

Helium is light and non-flammable, so it can be used to fill airships, balloons, thermometers, vacuum tubes, diving suits, etc. Liquid helium is invaluable in the field of cryogenics because of its extremely low boiling point. Liquid helium is mainly used in superconducting technology and magnetic resonance imaging (MRI). Superconducting particle accelerators use liquid helium to cool superconducting magnets. In the semiconductor industry, high purity helium is used as a guard gas for growing germanium and silicon crystals. An inert gas in the bottom, cleaning, shielding, and pressurizing systems of some mixtures. The U.S. space agency NASA is using helium-filled balloons to collect air samples from Antarctica to study the various causes of damage to the ozone layer.

Uses of neon gas:

Vacuum tubes, high pressure indicators, lightning rods, television fluorescent screens, helium-neon lasers, liquid neon are used as coolants, mercury and sodium vapor lamps, and for high-energy physics, filling spark Chambers with neon to detect the path of particles.

Uses of argon gas:

Argon gas is widely used in many aspects because of its properties of inertia and low heat transfer rate. The main use of argon is its inertia, which protects things that react easily with the surrounding material. Argon can be used as a protective gas for welding. Fillings in beer cans, though, can also be replaced with nitrogen; In pharmacy, high purity neon gas can be used to protect some intravenous healing drugs, such as acetaminophen, for example. Again, this is to prevent the drug from being damaged by oxygen and so on. The low heat transfer rate of argon is also one of its characteristics, such as it can be used as a filler between two layers of glass in an insulated window.

Uses of krypton gas:

Krypton is the main component of mixed gas in neon reference molecular laser, which can generate laser for semiconductor precision lithography. Krypton can also be used to make special flat glass for the solar energy, automotive and construction industries. Unique properties of krypton can be formed in glass coating process. Krypton 83 has been used in magnetic resonance imaging to distinguish between hydrophobic and hydrophilic surfaces. Krypton's numerous lines make the ionized krypton gas discharge tube white, and the light bulb into which krypton gas is injected is a very bright white light source, so it is often used as a photographic flash.

Uses of xenon gas:

Xenon was used for luminescence, including the xenon flash for photography. In 1962, bell LABS researchers discovered the laser effects of xenon, which interacts with a variety of different receptors and ion channels. Xenon is also used to start high pressure sodium lamps. Xenon has the lowest thermal conductivity and ionization energy of all non-radioactive noble gases. The luminescent body in the plasma display is equipped with xenon and neon and is converted to the plasma state by the electrode. The interaction between the plasma and the electrode produces ultraviolet light, which activates the phosphorous coating on the front of the display to emit visible light.
