What 𫒢 means
An old Chinese name for Hahnium, the proposed name for element 105. Researchers at the University of California, Berkeley proposed Hahnium in 1970 to honor German chemist Otto Hahn. A Chinese-language chemistry guide, Principles of Inorganic Chemistry Nomenclature (1980), used 𰾉 for Hahnium; 𫒢 is its traditional-script form.
The left-hand component marks a metal or chemical element; the right-hand component hints at its Chinese sound. This is a made-for-chemistry name, not an everyday word for “rare metal.”
Why did Hahnium give way to Dubnium?
Dubnium became the settled name for element 105 in 1997. The International Union of Pure and Applied Chemistry (IUPAC), the body that standardizes chemical names, settled a naming dispute: Berkeley researchers proposed Hahnium for chemist Otto Hahn, while a Soviet team proposed Nielsbohrium for physicist Niels Bohr. The chosen name honors Dubna, the Russian town where the Joint Institute for Nuclear Research is based.
Chinese chemical terminology authorities updated the element's name in 1998. The modern traditional Chinese form is 𨧀; the simplified form is 𬭊.
A specialist historical label in Chinese chemistry.
For modern Chinese element names, use 𨧀 in traditional script or 𬭊 in simplified script; 𫒢 is historical.
