Periodic Table -> Argon ArgonArgon DetailsArgon Symbol: ArArgon Atomic Number: 18Argon Atomic Weight: 39.948What is Argon?Argon (Ar, atomic number 18) is the third most common gas in the world, even more so than carbon dioxide. The word "argon" means inactive, inert in Greek and refers...
Introductionthe chemical symbol of Argon element is Ar, the atomic order is 18, located in group 18 of the periodic table, it is a rare gas. Argon accounts for 0.934% of the atmospheric volume (9340 ppmv), is the third largest gas in the Earth's atmosphere, is more than two times th...
argon (Ar), chemical element, inert gas of Group 18 (noble gases) of the periodic table, terrestrially the most abundant and industrially the most frequently used of the noble gases. Colourless, odourless, and tasteless, argon gas was isolated (1894) from air by the British scientists Lord...
