About
The character "氦" was formulated in the late 19th century as a direct representation of the chemical element helium following its scientific identification, constructed as a phono-semantic compound with the radical "气" indicating its gaseous nature and the component "亥" serving as a phonetic element to approximate the sound of the element's name. Since its creation, this character has solely denoted the inert gas helium, with its meaning and form remaining specifically tied to this scientific context without deviation.
