Abstract The fourth IUPAC/IUPAP Joint Working Party (JWP) on the priority of claims to the discovery of new elements 113, 115, 117 and 118 has reviewed the relevant literature pertaining to several claims. In accordance with the Criteria for the discovery of elements previously established by the 1991 IUPAC/IUPAP Transfermium Working Group (TWG), and reinforced in subsequent IUPAC/IUPAP JWP discussions, it was determined that the RIKEN collaboration has fulfilled those Criteria for element Z…

Names and symbols of the elements with atomic numbers 113, 115, 117 and 118 (IUPAC Recommendations 2016)

Abstract A joint IUPAC/IUPAP Working Party (JWP) has confirmed the discovery of the elements with atomic numbers (Z) 113, 115, 117 and 118. In accordance with the 2016 IUPAC guideline for naming new

On the discovery of new elements (IUPAC/IUPAP Report)

Abstract 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,

Discovery of new element, nihonium, and perspectives (PLENARY)

A new element 113 was searched by the reaction of Zn on Bi using a gas-filled recoil ion separator at the RIKEN linear accelerator facility. Totally three decay chains due to 113 were observed. The

How elements up to 118 were reached and how to go beyond

The new superheavy elements with Z=113, 115, 117, and 118 were recently accepted into the periodic table and have been named. Elements with Z≥112 are predominantly produced in 48 Ca-induced fusion

Discovery of New Element, Nihonium

The priority of the discovery of the element 113 was of-ficially assigned to the work that was carried out at RIKEN. The name and symbol of nihonium and Nh which was proposed to the element 113 by the

Gas-phase chemistry of element 114, flerovium

Element 114 was discovered in 2000 by the Dubna-Livermore collaboration, and in 2012 it was named flerovium. It belongs to the group 14 of the periodic table of elements. A strong relativistic

Evolution of the periodic table through the synthesis of new elements

Abstract This brief introduction to the synthesis and chemistry of elements discovered since 1940 is focused primarily on Z=93–118. The goal of this work is not to simply catalogue the nuclear fusion

TLDR
The question of the existence of the upper boundary of the Periodic System and the probable prospects for obtaining super-heavy elements with a nuclear charge of Z > 110, in particular a new category of them – 5g-elements has been discussed.

Search for Superheavy Nuclei

We describe the discoveries of new superheavy nuclei (a) with Z=107–112 produced in cold fusion reactions between 208Pb and 209Bi and beams of A > 50 and (b) with Z=113–118 in hot fusion reactions
