Argon

Description:

Argon is the third most common gas in the Earth’s atmosphere. It is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily non-reactive substances become reactive. It also has uses in incandescent and fluorescent lighting, and other types of gas discharge tubes. It makes a distinctive blue-green gas laser.
