Welcome to the Periodic Table of the Elements power trail; which begins at Mount Henry Bridge and continues south down the freeway cycle path. Please stay safe and enjoy the power trail.
Argon is a colourless and odourless gas present to a very small extent in the atmosphere. Argon is very inert (indeed it is referred to as one of the noble gases) 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. Today, the chemical symbol for argon is Ar but until 1957 it was simply A.
