Corbino's Right-Step Periodic Table

Published in the same year as Janet's Left-Step formulation, Corbino OM (1928) Riv Nuovo Cimento 5:LXI (and from here) produced a Right-Step version.

Commenting on this formulation, Valery Tsimmerman writes:

"Corbino saw what Janet failed to see: If blocks shifted by corresponding value of quantum number l, then the rows represent electronic shells and Janet saw what Corbino fained to see, namely the Janet rule, also known as Madelung rule. Both used rectangular boxes, but neither noticed the perimeter rule."

 

Thanks to Valery T for the tip!
