Question
Describe briefly the discovery of noble gases.
Answer
Several scientists discovered Noble gases in the late 19th century, including Henry Cavendish, John William Strutt (Lord Rayleigh), and William Ramsay. In 1894, Ramsay and Lord Rayleigh discovered argon, the first noble gas, by isolating it from the air. They later discovered helium, neon, krypton, and xenon by using a similar method of fractional distillation of liquid air. The name “noble gases” was given to this group of elements because they were thought to be chemically inert and did not easily react with other elements.
