About
The character 氟 is a modern phono-semantic compound. The gas radical 气 encloses the component 弗, indicating fluorine's gaseous state at room temperature, while 弗 provides the phonetic element. Invented during the standardization of Chinese chemical nomenclature, it approximates the first syllable of the English or Latin name for fluorine. Unlike characters with deep classical roots, 氟 has a single, precise scientific meaning and is used exclusively in chemistry, industry, dentistry, and environmental science to refer to the reactive halogen element and its compounds.
