A paper just accepted for publication (5 April 2010) in Physical Review Letters by Yu. Ts. Oganessian and others claims the synthesis of a new element with atomic number 117. The abstract states "The discovery of a new chemical element with atomic number Z=117 is reported. The isotopes 293 117 and 294 117 were produced in fusion reactions between 48 Ca and 249 Bk. [...]
Now that makes.....uh......non perfect sense....118 before 117.....where'd they learn to count?Henry J wrote:Nah, it just fills a hole in the periodic table, since element 118 got discovered before 117.
