Wheelshaped Table of Elements
From Facebook, a Wheelshaped table of elements.
Please note the symmetry of this representation.
As a result, it is possible that element 118 is the very last one in the periodic table. We have the sequence:
2 x 14 (blue)
4 x 10 (brown)
6 x 6 (violet)
8 x 2 (green)
and, logically, neither first nor last factor can be 0 or -2 (they differ in two columns above respectively by 2 and 4).
On the other hand, the coherence of the structure requires the existence of two additional elements at the beginning!
