About
The character "钷" is a modern creation specifically devised to denote the chemical element promethium, constructed as a phonosemantic compound where the simplified metal radical "钅" indicates its metallic nature and the right-hand component "叵" offers a phonetic cue, with its traditional form "鉕" employing the full metal radical "金" alongside the same phonetic element "叵", and since its introduction this character has consistently carried this singular scientific meaning without alteration.
