The Full Story
Argon was discovered in 1894 when Lord Rayleigh noticed that nitrogen from air was slightly denser than nitrogen prepared from chemical compounds. William Ramsay helped isolate the new gas, showing that a previously unknown element was present in the atmosphere. Argon’s discovery was important because it led to the recognition of the noble gases as a whole family. This discovery expanded the periodic table and explained why some gases were so unreactive.
