This
element is not currently measured in this laboratory.

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. 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.
