helium, He, atomic number 2(noun)
a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas)
An inert, monoatomic, gaseous element occurring in the atmosphere of the sun and stars, and in small quantities in the earth's atmosphere, in several minerals and in certain mineral waters. It is obtained from natural gas in industrial quantities. Symbol, He; atomic number 2; at. wt., 4.0026 (C=12.011). Helium was first detected spectroscopically in the sun by Lockyer in 1868; it was first prepared by Ramsay in 1895. Helium has a density of 1.98 compared with hydrogen, and is more difficult to liquefy than the latter. Chemically, it is an inert noble gas, belonging to the argon group, and cannot be made to form compounds. The helium nucleus is the charged particle which constitutes alpha rays, and helium is therefore formed as a decomposition product of certain radioactive substances such as radium. The normal helium nucleus has two protons and two neutrons, but an isotope with only one neutron is also observed in atmospheric helium at an abundance of 0.013 %. Liquid helium has a boiling point of -268.9
Origin: [NL., fr. Gr. "h`lios the sun.]
A colorless and inert gas, and the second lightest chemical element (symbol He) with an atomic number of 2 and atomic weight of 4.002602.
A form or sample of the element.
Origin: From helium, from ἥλιος (because its presence was first theorised in the sun's atmosphere).
a gaseous element found in the atmospheres of the sun and earth and in some rare minerals
Origin: [NL., fr. Gr. "h`lios the sun.]
Helium was an American alternative rock band formed during the summer of 1992. Under the original moniker of "Chupa," the band's founding members were Mary Lou Lord; Jason Hatfield, Juliana Hatfield's brother; Shawn King Devlin; and Brian Dunton. Devlin and Dunton were both also in the band Dumptruck before founding Helium.

hē′li-um, n. a substance discovered by Lockyer in the sun's atmosphere, found by Ramsay in the rare Norwegian mineral cleveite.

Helium. A noble gas with the atomic symbol He, atomic number 2, and atomic weight 4.003. It is a colorless, odorless, tasteless gas that is not combustible and does not support combustion. It was first detected in the sun and is now obtained from natural gas. Medically it is used as a diluent for other gases, being especially useful with oxygen in the treatment of certain cases of respiratory obstruction, and as a vehicle for general anesthetics. (Dorland, 27th ed)
Helium is simultaneously an online community for writers and a directory for user-generated articles. Writers can submit articles to 24 different channels (business, entertainment, travel, etc.), write for the side of a heated debate, try to capture publisher writing assignments bounties or win user-voted Helium writing contests. Users get to rate submitted articles so the best writing rises to the top. Community writers can also get paid for their work. Helium shares ad revenues with popular writers and the site has an extensive network of publishers that pay for specific articles that meet their criteria. Payments per article range from $20 to over $100, with 20% transaction fee going to Helium. Helium also has a partner program where partners can create their own branded Helium page with topics and debates that they choose. Partners are given co-branded advertisements to include on their sites and receive small donations for every visitor they send to the Helium site.
