The heaviest elements to have been chemically characterized are seaborgium (element 106), bohrium (element 107) and hassium (element 108). All three behave according to their respective positions in groups 6, 7 and 8 of the periodic table, which arranges elements according to their outermost electrons and hence their chemical properties. However, the chemical characterization results are not trivial: relativistic effects on the electronic structure of the heaviest elements can strongly… 
The impact of the properties of the heaviest elements on the chemical and physical sciences
Abstract The unique role of the heaviest elements in chemical and physical sciences is discussed. With the actinide series (Z = 90-103) and the superactinide series (Z = 122-155), the heaviest
Indication for a volatile element 114
Abstract Recently, the chemical investigation of element 112 revealed a highly volatile, noble metallic behaviour, as expected for the last group 12 member of the periodic table. The observed
Gas chemical properties of heaviest elements
Abstract Chemical studies at the upper end of the periodic table have reached atomic number 114. Recent experiments aiming at investigating chemical properties of elements Cn, 113, and 114 are

A test bench is established to challenge the validity and predictive power of modern fully relativistic quantum chemical models and to probe ‘relativistically’ influenced chemical properties and the architecture of the periodic table at its farthest reach.
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.
de Chemistry of the superheavy elements
The quest for superheavy elements (SHEs) is driven by the desire to find and explore one of the extreme limits of existence of matter. These elements exist solely due to their nuclear shell
Chemical studies of elements with Z ⩾ 104 in gas phase
Chemical investigations of superheavy elements in the gas-phase, i.e. elements with Z≥104Z≥104, allow assessing the influence of relativistic effects on their chemical properties. Furthermore, for

In this chapter, the chemical properties of the man-made transactinide elements rutherfordium, Rf (element 104), dubnium, Db (element 105), seaborgium, Sg (element 106), bohrium, Bh (element 107),
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.

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.
Chemical characterization of bohrium (element 107)
The chemical separation and characterization of six atoms of element 107 (bohrium, Bh), in the form of its oxychloride, is reported, finding that this compound is less volatile than the oxychlorides of the lighter elements of group VII, thus confirming relativistic calculations that predict the behaviour of bohrium to coincide with that expected on the basis of its position in the periodic table.
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,
Intermetallic compounds of the heaviest elements: the electronic structure and bonding of dimers of element 112 and its homolog Hg
Abstract Fully relativistic (four-component) density-functional calculations were performed for the element 112 dimers (112)X (X = Pd, Cu, Ag and Au) and those of its lighter homolog, Hg. A
Chemical identification and properties of element 112
Summary We present results of the second experiment on the chemical identification of element 112. Similar to the first test in 2000, we aimed at the production of the spontaneously fissioning 283112
Relativistic effects on experimentally studied gas-phase properties of the heaviest elements
Abstract Influence of relativistic effects on atomic properties and volatility of element 112 and its homolog Hg has been studied using results of relativistic atomic and molecular calculations.
