such problems, the IUPAC has made recommendation that until a new element’s discovery is proved, and its name is officially recognised, a systematic nomenclature be derived directly from the atomic number of the element using the numerical roots for and numbers - . These are shown in Table . . The roots are put together in order of digits which make up the atomic number and “ium” is added at the end.

Later permanent name and symbol are given by a vote of IUPAC representatives from each country. The permanent name might reflect the country (or state of the country) in which the element was discovered, or pay tribute to a notable scientist. As of now, elements with atomic numbers up to have been discovered.
Official names of all elements have been announced by IUPAC. Problem . What would be the IUPAC name and symbol for the element with atomic number ? From Table .
