Argon

Here is a brief description of argon.

•     Standard state: gas at 298 K
•     Colour: colourless
•     Classification: Non-metallic

Argon is colourless and odourless. Argon is very inert and is not known to form true chemical compounds. It makes a good atmosphere for working with air-sensitive materials since it is heavier than air and less reactive than N2.

Here is a brief summary of the isolation of argon.

Argon is present to a small extent in the atmosphere and is obtained as a byproduct from the liquefaction and separation of air. This would not normally be carried out in the laboratory and argon is available commercially in cylinders at high pressure.
