Chemical properties of element 106 (seaborgium) of chemical properties for the heaviest elements are predicted as a consequence of increasingly strong relativistic effects on the electronic shell structure. ... M Schaedel,W Bruechle,R Dressler,... - 《Nature》 被引量: 171发表: 1997年 Neutral ...
In December 2015, the Joint Working Party of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP), which evaluates claims of discovery of new elements, recognized the element and assigned the priority to the Russian–...
Fore.g.element 114 ([Rn]7s26d107p2)theenergy difference between the filled 7p1/2and empty 7p3/2orbital’s amounts to about 4 eV, which makes this elementa candidate for a very noble and volatile behavior [9]. Thismeans that in contrast to the lightest member of group 14to which ...
So, moving up to the next heaviest noble gas, you getradon. Radon does exist in nature and is an extremely dense gas. Radon has a density of around 4.4 grams per cubic centimeter. Most sources consider this element to be the heaviest noble gas. ...
