About
The character for sodium, "钠", was coined in the modern era to designate the chemical element, following the common Chinese practice of forming characters with a semantic radical and a phonetic component. Its traditional form, "鈉", combines the metal radical "金" to denote its metallic properties with "內" as a phonetic indicator, approximating the sound of "natrium", the Latin source of the element's name. In the simplified version, the metal radical is abbreviated to "钅" while the phonetic element is written as "内", preserving the original structural logic. Throughout its use, the character has maintained a singular and stable meaning, referring exclusively to the element sodium, which reflects its deliberate creation for scientific terminology without undergoing semantic shift.
