👤 whose
Whose work gave us the noble gases as a new group in the periodic table?
Quick Answer
William Ramsay’s. He discovered several noble gases in the 1890s and showed they formed a distinct family.
The Full Story
William Ramsay discovered argon in 1894 and later identified helium, neon, krypton, and xenon in the 1890s. These gases turned out to be exceptionally unreactive because their outer electron shells are complete. Their discovery added an entirely new group to the periodic table and changed ideas about chemical reactivity. Ramsay won the 1904 Nobel Prize in Chemistry for this work.
