argonon,inert gas,noble gas- any of the chemically inert gaseous elements of the helium group in the periodic table air- a mixture of gases (especially oxygen) required for breathing; the stuff that the wind consists of; "air pollution"; "a smell of chemicals in the air"; "open a wind...
Argon gas is prepared by fractionating liquid air. TheEarth's atmospherecontains 0.94% argon. Mars' atmosphere contains 1.6% Argon-40 and 5 ppm Argon-36. Toxicity Because it is inert, argon is considered to be non-toxic. It is a normal component of air that we breathe every day. Argon ...
Here's a collection of useful and interesting argon facts. Argon is the noble gas with element atomic number 18 with element symbol Ar.
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, andGeiger counters. It also is widely utilized as an inert atmosphere for arc-welding metals, such asaluminumandstainless steel; for the production and...
We are told that the noble gases, with their atomic numbers, are: helium 2, neon 10, argon 18, krypton 36, xenon 54, radon 86, and ununoctium 118.Thus, the sizes (number of elements) of the rings of electrons around the nucleus are the differences between the atomic numbers: 2, 8,...
