U+7839 "砹" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
U+7839 "砹" CJK Unified Ideograph-# is a Chinese character that primarily functions as a logogram representing the chemical element astatine, which is a rare, radioactive halogen. Its composition combines the radical 石 (stone or rock) on the left, suggesting a connection to minerals or solids, with the phonetic component 艾 (ài) on the right, which contributes to its pronunciation in Mandarin as "ài." Beyond its scientific usage in modern Chinese for astatine, the character appears less commonly in historical contexts and is not a frequent character in everyday language, mostly encountered in specialized chemical nomenclature. Its Unicode inclusion supports digital representation and text processing for East Asian languages, ensuring compatibility across systems that handle Classical and Simplified Chinese writing.
