About
The character "氮" was created in the late 19th century to designate the chemical element nitrogen, constructed through a phono-semantic process where the gas radical "气" denotes its state and the component "炎" provides phonetic approximation derived from "淡", meaning dilute, alluding to nitrogen's effect of reducing oxygen concentration in air. This deliberate formation reflects the method of coining terms for new scientific concepts within Chinese, and since its inception, the character has retained both its structural composition and its specific referent without alteration.
