U+7837 "砷" CJK Unified Ideograph-# Unicode Character
U+7837 "砷" CJK Unified Ideograph-# is a Chinese character representing the element arsenic, a toxic metalloid with chemical symbol As. In modern Chinese, it is commonly used in scientific and medical contexts, particularly in reference to arsenic compounds or poisoning, while historically it also denoted a type of stone or mineral. The character is composed of the radical for stone or mineral (石) on the left, indicating its earthy nature, and a phonetic component (申) on the right that approximates its pronunciation, which in Mandarin is "shēn." As part of the CJK (Chinese, Japanese, and Korean) unified ideograph block, it is integral to technical vocabulary across these languages, though its usage is less frequent in everyday writing due to the hazardous connotations of the substance it names.
