About
The character "氪" was constructed in modern times as a scientific term for the chemical element krypton, adhering to the naming pattern for noble gases in Chinese. Its structure is a phono-semantic compound, featuring the semantic component "气" which indicates its gaseous state, and the phonetic component "克" that supplies the approximate pronunciation. Since its creation, the character has been used exclusively to refer to this element, with no divergence in its meaning or structural form.
