Uses: Neon is used glow lamps, electron tubes, signs, plasma studies, fluorescent starter tubes, cryogenic refrigeration and gas lasers. Neon is a colorless, odorless, and tasteless monatomic gas, belonging to the Group VIIIA elements, called noble gases. Neon, the name of which is derived from the Greek word neos, new, is present in some minerals, but its only commercial source is the atmosphere, of which it comprises 18 parts per 1,000,000 by volume.
What is helium used for? Helium is put into balloons to help float Helium is easily detected in minute quantites, and has a very small molecule. So helium is also used for checking vacum and other â¦enclosures for leaks. Helium is used in some noble gas (neon) signs, possibly mixed with other gases. Liquid helium is used as a coolant, like for MRI magnets and such. Liquid helium acts as a study in physics for superfluids (see link below).
