ORNL actinides from HFIR (in parentheses) were involved in these superheavy element discoveries: flerovium-114 in 2000 (americium-243); moscovium-115 (americium-243), which was observed in 2004 ...
Moscovium (115 Mc) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no known stable isotopes. The first isotope to be synthesized was 288 Mc in 2004. There are five known radioisotopes from 286 Mc to 290 Mc. The longest-lived isotope is 290 Mc with a half-life of 0.65 seconds.
The discovery group intended to propose the name ghiorsium for element 118, but eventually the data were found to have been tampered and in 2002 the claims were withdrawn. Ghiorso's lifetime output comprised about 170 technical papers, most published in The Physical Review.
JINR in Dubna, Russia, led principally by Yuri Oganessian, in collaboration with several other labs including Lawrence Livermore National Laboratory (LLNL), since 2000: 114. flerovium, Fl, named after Soviet physicist Georgy Flyorov, founder of JINR (1999). 115. moscovium, Mc, named after Moscow Oblast, where the element was discovered (2004). 116.
It is expected that moscovium will have an inert-pair effect for both the 7s and the 7p 1/2 electrons, as the binding energy of the lone 7p 3/2 electron is noticeably lower than that of the 7p 1/2 electrons. This is predicted to cause +I to be a common oxidation state for moscovium, although it also occurs to a lesser extent for bismuth and ...
The FDIC is an independent government agency charged with maintaining stability and public confidence in the U.S. financial system and providing insurance on consumer deposit accounts.
Joe Burrow, Josh Allen and Kirk Cousins are all off in Week 12. Fantasy football owners will have some tough start/sit decisions in replacing them.
