Neon, inert gas. Export is possible.

Liquid neon is used as a cooler in cryogenic installations. Earlier neon was applied in the industry as an inert atmosphere, but has been forced out by cheaper argon. Fill with neon gas discharge tubes, signal lamps in the radio engineering equipment, photo cells, rectifiers. Mix of neon and helium use as a working environment in gaseous optical masers (helium - the neon laser). The tubes filled with mix of neon and nitrogen at a transmission through them an electric discharge give a red-orange luminescence in this connection they are widely used in advertizing. Neon lamps use for the alarm purposes on beacons and airfields as their red color very poorly dissipates fog and a haze.

The name happens from Greek νέος — new. There is a legend according to which the name to an element was given by the thirteen-year-old son Ramzaya — Willie who has asked the father as that is going to call new gas, having noticed at the same time that novum (Latin — new would like to name it). His father had liked this idea, however he has considered that the name neon formed from the Greek synonym will better sound.
