Almost every Chinese gas-element name takes the
气 (qì, gas) radical:
氢 hydrogen,
氧 oxygen,
氮 nitrogen,
氦 helium,
氖 neon,
氩 argon. The phonetic component
亚 (yà) gives the pronunciation. So
气 +
亚 →
氩 = 'the gas pronounced yà' = argon. Argon is colorless, inert, and makes up about 0.94% of Earth's atmosphere.
