Thus at this point in time we have not created individual element pages for elements 114 and above as they have not been officially named. Likewise we only list unnamed elements on our table above whose discovery has been tentatively recognized by IUPAC. Our policy is to only create individual element pages for elements on our periodic table that have been officially recognized and named by the International Union of Pure and Applied Chemists (IUPAC).
