Lord Rayleigh (Discovery of Noble Gases) (jan 1, 1894 – jan 1, 1894)
Description:
Rayleigh discovered argon, the first of the noble gases, after noticing a discrepancy in the density of nitrogen from the air compared to nitrogen from chemical compounds.
Example: Argon (Ar) is the noble gas discovered by Rayleigh. It was the first noble gas to be identified and doesn't react with other elements under normal conditions because it is a stable element
