Character Story & Explanation
氚 (chuān) means tritium, a radioactive isotope of hydrogen with one proton and two neutrons. It is used in nuclear fusion research and luminous devices like self-powered lighting. The radical 气 (qì, gas) indicates gaseous elements, and the phonetic component 川 (chuān) suggests pronunciation. Unlike Western terms derived from Greek 'tritos' (third), 氚 directly combines 'gas' with a phonetic element.
