U+6C2A "氪" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

U+6C2A "氪" CJK Unified Ideograph-# is a Chinese character that primarily represents the chemical element krypton, where it is used in modern Chinese scientific terminology to denote this noble gas. Its structure combines the radical 气, meaning gas or air, with the phonetic component 克, which provides a clue to its pronunciation of "kè" in Mandarin. This character was encoded in the Unicode standard as part of the CJK (Chinese, Japanese, Korean) unified ideographs block, which encompasses historical and modern logographic characters used across these East Asian languages. In addition to its scientific usage, "氪" may appear in transliterations of foreign names or terms, reflecting the adaptability of Chinese script for technical and global contexts.
