氢
U+6C22 "氢" CJK Unified Ideograph-# is a Chinese character that represents the chemical element hydrogen.

This character is widely used in modern Chinese, particularly in scientific contexts such as chemistry, where it forms words like "氢气" (hydrogen gas) and "氢原子" (hydrogen atom). As part of the CJK Unified Ideographs block, it enables digital representation and exchange of this essential term across various platforms and languages that use Chinese script.
