U+6C21 "氡" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
氡
U+6C21 "氡" CJK Unified Ideograph-# is the standard encoding for the Chinese character that represents the chemical element radon. In modern Chinese, it is used to denote the radioactive noble gas with atomic number 86, and its formal translation in Chinese chemistry terminology is "radon," following the pattern of using a "气" (gas) radical for gaseous elements. This character is a relatively recent addition to the character set, as it was created in the 20th century to standardize the Chinese name for this element, which was previously referred to by other terms.
