ELEMENT DISCOVERY
Argon was discovered in 1894 by Lord Rayleigh and William Ramsay, after it was separated from air, in which it is commonly found. It had been previously noted by Henry Cavendish as the 1% of air that would not react to any condition, as it is a noble gas.

USES OF ARGON
Argon has many purposes, including its use in the above photo, for welding. Argon is also used in some light bulbs and fluorescent tubes. Argon is also used as a protective blanket for growing silicon and germanium crystals.
WHERE IS IT FOUND?
Argon, making up .94% of Earth's atmosphere, is extractable from the air, and as such is found abundantly.
