Application of inert gases

Inert gases, also known as noble gases, are a group of chemical elements that are highly unreactive due to their full valence electron shells. They include helium, neon, argon, krypton, xenon, and radon. These gases are not combustible and do not form chemical compounds under normal conditions, which makes them useful in a variety of applications:

• Helium is used as a lifting gas in balloons and airships, as well as in cryogenics and MRI scanners.

• Neon is used in neon lights and advertising signs, as well as in high-voltage indicators and plasma tube displays.

• Argon is used in welding and metal fabrication, as well as in the production of light bulbs and fluorescent tubes. It is also used as a refrigerant and in the production of semiconductors.

• Krypton is used in the production of flash lamps and strobe lights, as well as in the creation of high-intensity discharge lamps.

• Xenon is used in the production of flash lamps and strobe lights, as well as in the creation of high-intensity discharge lamps and in medical imaging.

• Radon is a naturally occurring radioactive gas that is found in small amounts in the earth's atmosphere. It is used in the production of radon-222, which is used as a tracer in medical imaging.

In addition to these specific applications, inert gases are also used as a protective gas in various chemical reactions, as they can prevent the reaction from being contaminated by other gases in the atmosphere. They are also used in the production of semiconductors, as well as in the preservation of artefacts and works of art.
