Priority for the discovery of the elements with atomic numbers 114 and 116 has been assigned, in accordance with the agreed criteria, to collaborative work between scientists from the Joint Institute for Nuclear Research in Dubna, Russia, and from Lawrence Livermore, California, USA (the Dubna-Liv...
BEFORE 1940, chemistry did not know of any element with atomic number greater than 92 (uranium). In spite of occasional claims to the contrary scattered throughout the literature, there still is no good evidence that such elements exist in Nature, except perhaps for minute amounts formed from ...

Every time you have one more proton you have another element, and then— oops— there'd be an atomic number for which there was no known element. And the uh prediction was that an element with that atomic number existed somewhere, but it just hadn't been found yet. And its location ...
