Argon is a colorless, odorless noble gas that is chemically inert under most conditions and abundant in Earths atmosphere.
Properties of Argon | It has low reactivity, moderate density among noble gases and is used where an inert atmosphere is required.
Uses of Argon | Argon is used in welding shielding, incandescent and fluorescent lighting and as an inert gas for laboratory work.
Isotopes of Argon | Stable isotopes include Ar 36, Ar 38 and Ar 40; argon is nonreactive but can cause asphyxiation in confined spaces by displacing oxygen.
