About
The character "镎" was devised in the twentieth century to represent the synthetic element neptunium, adhering to the pattern of Chinese element names that incorporate a semantic radical for metal and a phonetic component; its traditional form "鎿" explicitly pairs the metal radical 金 with the phonetic "拿" to indicate the pronunciation "ná", whereas the simplified form "镎" employs the abbreviated metal radical "钅" alongside the phonetic "纳", which carries a similar initial sound, and the character has exclusively denoted this chemical element since its creation without any shift in meaning.
