About
This character is a modern phono-semantic compound created for the Chinese periodic table. The semantic radical 石 on the left classifies it as a solid non-metallic element at room temperature. The component 西 on the right serves as the phonetic element, approximating the initial sound of "selenium". Lacking ancient etymology or literary usage, 硒 was coined specifically to translate a foreign scientific term, combining a material classifier with a phonetic match in the standard manner for chemical nomenclature.
