Subsequent work at the JINR laboratory at Dubna, led by Yuri Oganessian and a Russian-American team of scientists, was successful in identifying elements 113–118 (113, nihonium; 114, flerovium; 115, moscovium; 116, livermorium; 117, tennessine and 118, oganesson), thereby completing the Period 7 elements of the periodic table of the elements.
moscovium, Mc, named after Moscow Oblast, where the element was discovered (2004). 116. livermorium, Lv, named after Lawrence Livermore National Laboratory, a collaborator with JINR in the discovery (2000). 117. tennessine, Ts, after Tennessee, where the berkelium target needed for the synthesis of the element was manufactured (2010). 118.
Einsteinium and fermium were discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the composition of radioactive debris from the detonation of the first hydrogen bomb. [19] The isotopes synthesized were einsteinium-253, with a half-life of 20.5 days, and fermium-255 , with a half-life of about 20 hours.
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 ...

Complete and accurate calculations are not available for elements beyond 123 because of the extreme complexity of the situation: [55] the 5g, 6f, and 7d orbitals should have about the same energy level, and in the region of element 160 the 9s, 8p 3/2, and 9p 1/2 orbitals should also be about equal in energy.
For this taste test, we selected seven canned bottles of whipped cream and five tubs of whipped cream to try. We transferred the whipped cream from the bottles and tubs to plates so editors could ...
