As the chase for new elements slows, scientists focus on deepening their understanding of the superheavy ones they already know. As the chase for new elements slows, scientists focus on deepening their understanding of the superheavy ones they already know. 

The periodic table of the elements: the search for transactinides and beyond

The periodic table of Mendeleev, initially proposed on the basis of 66 elements, and containing 82 elements at the time of Moseley (1887–1915), describes nowadays 118 elements. The huge challenge of

Lead Kindly Light:Spectroscopy and the Periodic Table

THE first part of the title that I have chosen is actually the title of a well-known poem from the 19th century poet John Newman. Its Kannada version by the erudite professor, B. M. Srikantaiah, is

The existence of the then-so-called inert gases was discovered over a short period of time in the 1890s; the demonstration that they were in fact not inert took place during an even shorter period of

Controversies, compromises and the common chemical language

The International Union of Pure and Applied Chemistry — whose 100th anniversary fittingly falls during the International Year of the Periodic Table — is most recognized for its role in the naming of

The periodic table and the physics that drives it

Mendeleev’s introduction of the periodic table of elements is one of the most important milestones in the history of chemistry, as it brought order into the known chemical and physical behaviour of

The International Year of the Periodic Table of the Chemical Elements (IYPT), which marks the sesquicentennial of the iconic chart’s introduction by Dmitri Mendeleev in 1869, provides a unique

Challenges for the Periodic Systems of Elements: Chemical, Historical and Mathematical Perspectives.

It is shown that ordered hypergraphs may solve current issues such as order reversals in super-heavy elements and lack of system predictive power, and proposes bringing back chemistry to the systems by exploring similarity and order relationships of elements using the current information of the chemical space.

Co-precipitation behaviour of single atoms of rutherfordium in basic solutions

A co-precipitation method with samarium has now been developed that suggests rutherfordium would form hydroxide precipitates—but not ammine ones—if it were possible to perform these experiments on macroscopic quantities.

Understanding Periodic and Non-periodic Chemistry in Periodic Tables

It is essential that Periodic Tables display important trends in element chemistry, and the combination of experimental data and theoretical insight supports a more nuanced understanding of complex periodic trends and non-periodic phenomena.



The Chemistry of Transactinide Elements-Experimental Achievements and Perspectives

The chemistry of transactinides and superheavy elements has reached element 108. Preparations are under way to leap to element 112 and beyond. This development, its current status and future

Chemical properties of element 106 (seaborgium)

The synthesis, via nuclear fusion reactions, of elements heavier than the actinides, allows one to probe the limits of the periodic table as a means of classifying the elements. In particular,

Chemical investigation of hassium (element 108)

Evidence that the chemical properties of hassium and its lighter homologue osmium are similar is provided, thus confirming that hassio exhibits properties as expected from its position in group 8 of the periodic table.

Superheavy element flerovium (element 114) is a volatile metal.

A gas-solid chromatography study of the adsorption of Fl on a Au surface points to the formation of a metal-metal bond of Fl with Au, the least reactive element in the group, but still a metal.

Measurement of the first ionization potential of lawrencium, element 103

The present work provides a reliable benchmark for theoretical calculations and also opens the way for IP1 measurements of superheavy elements (that is, transactinides) on an atom-at-a-time scale.

Atom-at-a-time laser resonance ionization spectroscopy of nobelium

Optical spectroscopy of a primordial isotope has traditionally formed the basis for understanding the atomic structure of an element. Such studies have been conducted for most elements and

Reactivity of Superheavy Elements Cn, Nh, and Fl and Their Lighter Homologues Hg, Tl, and Pb, Respectively, with a Gold Surface from Periodic DFT Calculations.

The obtained trend in the adsorption energy, Nh ≫ Fl > Cn, enables one to easily separate these elements from each other, as well as from their lighter homologues using gold or gold/quartz surfaces.

First Ionization Potentials of Fm, Md, No, and Lr: Verification of Filling-Up of 5f Electrons and Confirmation of the Actinide Series.

These results clearly demonstrate that the 5f orbital is fully filled at No with the [Rn]5f147s2 configuration and that Lr has a weakly bound electron outside the No core, and unequivocally verify that the actinide series ends with Lr.

Electron and Nucleon Localization Functions of Oganesson: Approaching the Thomas-Fermi Limit.

Fermion localization functions are used to discuss electronic and nucleonic shell structure effects in the superheavy element oganesson, the heaviest element discovered to date, and the nucleon localization in Og is predicted to undergo a transition to the Thomas-Fermi gas behavior in the valence region.
