About
The character 钚, with its traditional form 鈈, is a phono-semantic compound created to name the radioactive element plutonium. Its left side features the metal radical 钅 (simplified) or 金 (traditional), classifying it as a solid metallic element within the standard naming system for actinides. The right side uses the character 不 purely as a phonetic component, approximating the "plu" or "bu" sound from its international name. Like many characters for synthetic elements, it has no ancient origin, being a modern construction that fits nuclear terminology into the existing Chinese writing framework.
