  2. Ununennium - Wikipedia

    en.wikipedia.org/wiki/Ununennium

    Ununennium, also known as eka-francium or element 119, is a hypothetical chemical element; it has symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element has been discovered, confirmed, and a permanent name is decided upon.

    The first two elements of period 8 will be ununennium and unbinilium, elements 119 and 120. Their electron configurations should have the 8s orbital being filled. This orbital is relativistically stabilized and contracted; thus, elements 119 and 120 should be more like rubidium and strontium than their immediate neighbours above, francium and ...

    Neither element 119 nor element 120 was observed. This implied a limiting cross-section of 65 fb for producing element 119 in these reactions, and 200 fb for element 120. [21] [10] The predicted actual cross section for producing element 119 in this reaction is around 40 fb, which is at the limits of current technology. [20]

    This experiment used a 249 Bk target and a 50 Ti beam to produce element 119, but since 249 Bk decays to 249 Cf with a half-life of about 327 days, both elements 119 and 120 could be searched for simultaneously: 249 97 Bk + 50 22 Ti → 299 119 Uue * → no atoms 249 98 Cf + 50 22 Ti → 299 120 Ubn * → no atoms. Neither element 119 nor ...

    Scientists discovered a method to create element 116 using a titanium beam, paving the way for future synthesis of element 120, the "holy grail" of chemistry. ... To make elements 119 or 120, the ...

    The next element below francium (eka-francium) in the periodic table would be ununennium (Uue), element 119. [ 36 ] : 1729–1730 The synthesis of ununennium was first attempted in 1985 by bombarding a target of einsteinium -254 with calcium -48 ions at the superHILAC accelerator at the Lawrence Berkeley National Laboratory in Berkeley, California.

  8. Naming of chemical elements - Wikipedia

    The recommendations are mostly ignored among scientists, who simply call these elements by their atomic number, for example "element 119" (instead of "ununennium"), with the symbol of (119) or even simply 119. [39]
