The story of the word

Rayleigh and Ramsay isolated the gas in 1894 and named it for what it refused to do: ἀργόν is the neuter of ἀργός, idle, itself a contraction of ἀ-εργός, not working. Argon will not combine with anything under ordinary conditions, which is exactly why it fills light bulbs and shields the weld pool in arc welding. The ἔργον inside it also sits in energy, ergonomics, and surgery, which is χειρουργία, hand-work.
