Argon is the commonest noble gas, making up nearly one per cent of the earth's atmosphere.
Where can be found?
Argon is the most abundant of the noble gases in the earth´s atmosphere. It constitutes nearly 1%  of the volume of air making it the third most abundant element in air after nitrogen and oxygen. Argon is also found in small traces in the earth's crust and ocean waters.
