“…The following years saw a number of consultations and exchange of letters in order to find agreement with IUPAC, IUPAP, and the laboratories on discovery and naming of the elements from 101 to 109. A final IUPAC Recommendation for the names and symbols of the transfermium elements with atomic number 101 to 109 was published in 1997 [4]. It was accepted also by IUPAP and the scientists of the involved laboratories.…”

“…The achievement for physical and chemical properties resulting from the discovery of the new nuclei and elements is presented in Sect. 4. On the basis of this information and considering theoretical predictions, we estimate possible experimental developments and results for production and identification of new isotopes of new elements beyond oganesson, element 118, in Sect.…”

Almost thirty years ago the criteria that are currently used to verify claims for the discovery of a new element were set down by the comprehensive work of a Transfermium Working Group, TWG, jointly established by IUPAC and IUPAP. The recent completion of the naming of the 118 elements in the first seven periods of the Periodic Table of the Elements was considered as an opportunity for a review of these criteria in the light of the experimental and theoretical advances in the field. In late 2016 the Unions decided to establish a new Joint Working Group, JWG, consisting of six members determined by the Unions. A first meeting of the JWG was in May 2017. One year later this report was finished. In a first part the works and conclusions of the TWG and the Joint Working Parties, JWP, deciding on the discovery of the now named elements are summarized. Possible experimental developments for production and identification of new elements beyond the presently known ones are estimated. Criteria and guidelines for establishing priority of discovery of these potential new elements are presented. Special emphasis is given to a description for the application of the criteria and the limits for their applicability.

“…89 O nome roentgênio foi proposto pelos descobridores alemães em homenagem a Wilhelm Conrad Roentgen (1845-1923), pela descoberta dos raios-X, que lhe deu o primeiro prêmio Nobel de Física da História. 90 O copernício (Cn, Z=111) foi preparado em 1996 no GSI pelo bombardeamento de 208 Pb com 70 Zn. 91 De acordo com recomendações da IUPAC em 2009 recebeu o nome de copernício em honra a Nicolau Copérnico (1473-1543), o grande astrônomo polonês.…”

ORIGINS AND CONSEQUENCES OF THE PERIODIC TABLE, THE MOST CONCISE ENCYCLOPEDIA CREATED BY MANKIND. The slow process of the discovery of the elements led to a need to investigate their relations with one another; this was the path, which ultimately produced Mendeleev's classification, the ancestor of the present Periodic Table. Once established, the Table, in its turn, became a guiding thread leading to the discovery of yet other new elements. This whole process can be likened to a two-way avenue, the first way leading to the establishment of the classification, whereas the latter, once established, inverted the traffic, completing our present 118-element Periodic Table. In this sesquicentennial year of its inception, it is appropriate to survey the fascinating history of the long and arduous path of the creation of what can be rightly called the most concise encyclopedia devised by the human mind.

“…claims, the JWP has agreed that the priority of the Hofmann et al collaboration's discovery of element 111 at GSI is acknowledged" [13]. The name roentgenium was officially accepted in 2003 [170]. Seven roentgenium isotopes have been reported.…”
