About

氟 is a modern phono-semantic compound created for the element fluorine. The gas radical 气, which encloses the character, marks it as a gas, while the inner component 弗 supplies the pronunciation, approximating the first syllable of the English or Latin name. It was coined during the standardization of Chinese chemical nomenclature and is used exclusively in chemistry, industry, dentistry, and environmental science to refer to the highly reactive halogen gas and its compounds.
