Argon is an inert, colorless and odorless element — one of the Noble gases.Used in fluorescent lights and in welding, this element gets its name from the Greek word for "lazy," an homage to how little it reacts to form compounds.
By Chemicool's calculations, that translates to 65 trillion metric tons — and the number increases over time as potassium-40 decays.
According to the Jefferson National Linear Accelerator Laboratory, the properties of argon are: The first hint of argon's existence came in 1785, when British scientist Henry Cavendish reported a seemingly inert portion of air, according to the RSC.
Cavendish wasn't able to figure out what this mysterious 1 percent was; the discovery would come more than a century later, in 1894.
Working concurrently and in communication with Lord Rayleigh (John William Strutt), Scottish chemist William Ramsey identified and described the mysterious gas.
Because argon is inert, it is used in industrial processes that require a non-reactive atmosphere.
Examples, according to gas supply company Praxair, include welding specialty alloys and producing semiconductor wafers.
Argon is also a good insulator, so it's often pumped into deep-sea diving dry suits to keep the diver warm.
The two shared the Nobel Prize in Chemistry in 1904 for the discovery.
Argon led to other eureka moments for Ramsey, as well.
