Ar-40 Information

Argon is a monatomic noble gas. It makes up 0.93% of the air. Argon is a colourless, odorless element. It is inert and has no true compounds. Lord Rayleigh and Sir William Ramsey identified argon in 1894. Argon has 26 isotopes, 3 of them are stable and naturally occurring.

Argon is used in lighting products. It is often used in filling incandescent light bulbs. Some compounds of argon are mixed with krypton in fluorescent lamps. Crystals in the semiconductor industry are grown in argon atmospheres.
