About
钠 is a phono-semantic compound that combines the metal radical 钅 with the phonetic component 内. The traditional form 鈉 uses the full metal radical 金. Created as a modern scientific coinage, it designates the chemical element sodium and follows the periodic table convention of using the metal radical for metallic elements. The phonetic 内 was chosen to approximate the sound of the element's Western name, and the character had no historical meaning before the introduction of modern chemistry.
