Neon and Argon – About Elements

Neon

Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.

Argon

Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv). Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning.

Neon and Argon – Applications

Neon

Neon is often used in signs and produces an unmistakable bright reddish-orange light. Although tube lights with other colors are often called “neon”, they use different noble gases or varied colors of fluorescent lighting. Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen.

Argon

The major applications of argon include the following: electric lamps as filler gas, welding purpose, discharge tubes, argon lasers and argon-dye lasers. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon is also used in incandescent, fluorescent lighting, and other gas-discharge tubes.
