The chemical element of atomic number 18, an inert gaseous element of the noble gas group. Argon is the most common noble gas, making up nearly one percent of the earth's atmosphere,
  1. The chemical element of atomic number 18, an inert gaseous element of the noble gas group. Argon is the most common noble gas, making up nearly one percent of the earth's atmosphere

  1. a colorless and odorless inert gas; one of the six inert gases; comprises approximately 1% of the earth's atmosphere
  2. Argon is a chemical element represented by the symbol Ar. Argon has atomic number 18 and is the third element in group 18 of the periodic table (noble gases). Argon is the third most common gas in the Earth's atmosphere, at 0.93%, making it more common than carbon dioxide. ...
  3. The Argon was made by Grannaway Engineering Co, Earls Court, London S.W. in 1908. It was a fairly large touring car using a 25 hp 6-cylinder Coventry-Simplex engine. It was priced at 750 pounds. ...
  4. In the fiction of J. R. R. Tolkien, Argon was the fourth child of Fingolfin, High King of the Noldor in Beleriand.
  5. KH-5 ARGON was a series of reconnaissance satellites produced by the United States from February 1961 to August 1964. The KH-5 operated similarly to the Corona series of satellites, as it ejected a canister of photographic film. ...
  6. Argon is a genus of skippers in the family Hesperiidae.
  7. a chemical element (symbol Ar) with an atomic number of 18
  8. A nontoxic gas that many window manufacturers use instead of air between panes of insulated glass. Argon has higher insulation value than air and won't degrade the window's low-e coating like air will.
  9. An odorless, colorless, tasteless, nontoxic gas that is six times denser than air. Replacing the air between two panes of glass with argon gas reduces temperature transfer, making the surface of the glass inside the house closer to the inside temperature.
  10. An inert, nontoxic gas used in insulating glass units to reduce heat transfer.
  11. A gas known for its high atomic weight and properties as an insulator. Potential applications in diving include its use as an insulator in drysuit diving.
  12. A colorless, odorless element. Uses include shield in arc welding, furnace brazing, electric and specialized light bulbs and for use in geiger-counting tubes, and lasers. Hazard: May cause dizziness and drowsiness and rapid suffocation. In liquid form, is extremely cold and may cause frostbite.
  13. An inert gas that makes up less than one percent of air (sometimes used as a dry suit gas).
  14. An inert gas used in CFLs to regulate the environment inside the glass tubing so that the mercury vapor can absorb the electrical currents.
  15. (Ar) constitutes 1.3 percent of the atmosphere by weight and 0.94 percent by volume. Argon is isolated on a large scale by the fractional distillation of liquid air. It is used in gas-filled electric light bulbs, radio tubes, and Geiger counters. ...
  16. An odorless, colorless gas used to replace air between glass panes. Being heavier than air, it slows heat loss.
  17. A colorless, odorless inert gas sometimes used in the spaces between the panes in energy efficient windows. This gas is used because it will transfer less heat than air. Therefore, it provides additional protection against conduction and convection of heat over conventional double-pane windows.
  18. An inert gas typically used in deposition systems.
  19. An inert gas from the Earth’s atmosphere that is used inside most light bulbs.
  20. a gas used between the glass panes in some insulated glazing units
  21. A noble gas, used in light bulbs, gas discharge lamps, lasers, and Geiger Counters.
  22. A colorless, inert gas commonly found in air in small volumes. Its inert properties make it ideal for filling the air space of insulated glass units. Using Argon reduces air convection within the sealed air space, increased dimensional stability of the air space and reduces noise infiltration.
  23. Inert gas element utilized as a shielding component of "gas metal arc welding" (GMAW) or "metal inert gas welding" (MIG). Generally utilized when welding aluminum or like materials.
  24. Argon is a naturally occurring gas, which properties include being a low thermal conductor and is used for thermal insulation in energy efficient glazed units.
  25. Inert gas used in incandescent and fluorescent lamps. In incandescents, argon helps retard the evaporation of the tungsten filament.
