18 Ar Argon

Noble gas, mass: 39.948 u, 3 stable isotopes (36, 38, 40), abundance rank (earth/space): 53/11

Click image to magnify. Vial of glowing ultrapure argon. Original size in cm: 1 x 5. How to make gases glow.
Argon Also argon
Our air consists to 1% of argon, which makes it an abundant element in our direct vicinity. Therefore it is the cheapest and most frequently used noble gas, which comes into operation, when an inert atmosphere is needed, like in this cerium vial.
