Definition of the Argon Element
A colorless, odorless, inert gaseous element constituting approximately one percent of Earth's atmosphere, from which it is commercially obtained by fractionation for use in electric light bulbs, fluorescent tubes, and radio vacuum tubes and as an inert gas shield in arc welding.

Origin / Meaning of the name Argon
The name originates from the Greek word 'argos' meaning inactive.

Classification of the Argon Element
Argon is classified as an element in the 'Noble Gases' section which can be located in group 18 of the Periodic Table.

Facts about the Discovery and History of the Argon Element
Argon was discovered by Sir William Ramsey in 1894

Occurrence the Argon Element
The atmosphere contains only 0.94% volume of argon (1.29% mass)

Associated Uses of Argon
Electric light bulbs

Argon and the Periodic Table
Check out Argon on the Periodic Table which arranges each chemical element according to its atomic number, as based on the periodic law, so that chemical elements with similar properties are in the same column. Our Periodic Table is simple to use - just click on the symbol for Argon for additional information and for an instant comparison of the Atomic Weight, Melting Point, Boiling Point and Mass - G/cc with any other element. An invaluable source of facts and information as a Chemistry reference guide.

Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Argon is just one element that can be found.
