The Waterbe Humtus á Sectona é Iunctuanto has guidlines for the naming of elements, which are used officially by the Waterbe Empire.
The nomenclature is simple: The word 'Sectona' followed by the number of protons, then á, then the number of neutrons. This allows it to easily show the isotope. For scenarios where isotope is not important, the number of neutrons is not required.
The WHSI also has a database of common names used for elements. It does not recommend use of them for official purposes. The common names are still sometimes used in interprovince trades.
