Joe Howard [|Argon, Ar] Boiling point: -185.8C Melting point: 189.3C Density: 1.784g/l Protons/Electrons: 18 - Neutrons: 22 Atomic Mass: 39.948 Atomic Number: 18 Valence electrons: 8 Electron Config/ Orbital Notation: 1s2 2s 2 2p6 3s2 3p6 [Ne] 3s2 3p6 Cost or Value: $0.5 per 100g Argon is about 0.93% of the earth's atmosphere, which makes it the third most abundant gas. Argon is obtained from the air as a byproduct of the production of oxygen and nitrogen. William Ramsey and Lord Rayleigh Discoverd Argon in 1894. It is produced from looking at the residue and removing oxygen, nitrogen, carbon dioxide, and water from clean air. (Liquefication or Seperation) [|www.webelements.com]

Some Physical/Chemical properties are: Its critical temperature is 150.8. Argon is a noble gas. It is colorless, odorless and extremely unreactive. Its liquid range is 3.5K. It is also inert. It can be found in one compound, which is Argon Flourohydride, (HArF). Chemical reactions of argon is that it dissolves in water at a certain point and when an electric current gets it it glows a rich sky-blue color. It is used in light bulbs, an inert gas shield for arc welding and cutting, and a blanket for the production of titanium.
