Clarice Evone Phelps (née Salone) [1] is an American nuclear chemist researching the processing of radioactive transuranic elements at the US Department of Energy's Oak Ridge National Laboratory (ORNL). She was part of ORNL's team that collaborated with the Joint Institute for Nuclear Research to discover tennessine (element 117). [2]
According to guidelines of IUPAC valid at the moment of the discovery approval, the permanent names of new elements should have ended in "-ium"; this included element 117, even if the element was a halogen, which traditionally have names ending in "-ine"; [83] however, the new recommendations published in 2016 recommended using the "-ine ...
Element 117 was named tennessine because of the participation of Oak Ridge National Laboratory, Vanderbilt University and the University of Tennessee.
There was also an investigation conducted into Ninov's previous unsupervised science at GSI; it was found that "two sightings were spuriously created" (one of element 110 and another of element 112). [1] [9] However these false sightings were found amongst a large amount of real data that still supported his co-discoveries of elements 110 and ...
The periodic table could soon welcome a new element - it's currently unnamed but known as the super heavy element 117. You might want to sit down - it's time for a science lesson. "It's really ...
The heaviest discovery to date, element 118 oganesson, was made using a beam of calcium isotope 48 particles. Calcium 48, with its definitive 20 protons plus 28 neutrons, is a common and very ...
The scientists involved in the discovery of element 118, as well as those of 117 and 115, held a conference call on 23 March 2016 to decide their names. Element 118 was the last to be decided upon; after Oganessian was asked to leave the call, the remaining scientists unanimously decided to have the element "oganesson" after him.
In 1999, researchers at Lawrence Berkeley National Laboratory made use of these predictions and announced the discovery of elements 118 and 116, in a paper published in Physical Review Letters, [55] and very soon after the results were reported in Science. [56] The researchers reported to have performed the reaction. 86 36 Kr + 208 82 Pb → ...
