Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds. [9] In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen.
According to the vice-director of JINR, the Dubna team originally wanted to name element 116 moscovium, after the Moscow Oblast in which Dubna is located, [76] but it was later decided to use this name for element 115 instead. The name livermorium and the symbol Lv were adopted on May 23, [77] 2012.
Due to their short half-lives (for example, the most stable known isotope of seaborgium has a half-life of 14 minutes, and half-lives decrease with increasing atomic number) and the low yield of the nuclear reactions that produce them, new methods have had to be created to determine their gas-phase and solution chemistry based on very small ...
With the longest-lived isotope of technetium, 97 Tc, having a 4.21-million-year half-life, [10] no technetium remains from the formation of the Earth. [ 11 ] [ 12 ] Only minute traces of technetium occur naturally in Earth's crust—as a product of spontaneous fission of 238 U, or from neutron capture in molybdenum —but technetium is present ...
All element articles and their infoboxes use IUPAC spelling of elements and compounds. Notably, that is aluminium, sulfur, caesium , not aluminum, sulphur, cesium . For other English variant words (vapor vs. vapour) the infobox reads |engvar= .
