U+91F7 "釷" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
釷
U+91F7 "釷" CJK Unified Ideograph-# is a Chinese character (hanzi) that represents the element thorium, a radioactive metal, and is composed of the radical for gold or metal (釒) on the left and the phonetic component 土 (meaning earth or soil) on the right, which also suggests its pronunciation as "tǔ" in Mandarin. This character is primarily used in scientific and chemical contexts within the Chinese writing system to denote the atomic number 90 element, and it is also employed in Japanese (as a kanji) with similar chemical meanings. As part of the CJK (Chinese, Japanese, Korean) unified ideographs block, it was encoded in Unicode 1.1 in 1993 to facilitate digital representation of East Asian text.
