WHEN AND HOW THE ELEMENT WAS DISCOVERED

Sir William Ramsay and Lord Rayleigh in Scotland discovered argon in 1894. Argon was the residue found after removing nitrogen, oxygen, carbon dioxide, and water from air. Air contains less than .93% of argon. Argon is the third most abundant gas.

 

 

WHERE AND HOW THE ELEMENT IS OBTAINED OR PRODUCED

Argon is obtained from the air as a result of the production of oxygen and nitrogen.
