Description: Named from the Greek word meaning "inactive", argon is a colorless, odorless gas. Like helium and neon, argon is inert towards most other elements and chemicals. Unlike the other noble gases, argon is present in significant quantities in the atmosphere, making up nearly 1 % of it. Argon is used where ever an inert atmosphere is needed, such as inside light-bulbs, producing reactive metals, such as titanium, or in welding. Since it is more common, it is generally cheaper than other inert gasses.
