@Everyone. I think the time is ok, but if people want I'll shave a minute off.
The problem with periodic tables is they all treat the lanthanides and actinides differently when they move them down to that lower chunk. Because of that, elements 57/71 and elements 89/103 occupy those two slots between 56|72 and 88|104 depending on what table you use (and sometimes, like on the Sporcle quiz, neither element is put into that slot). So, I have counted those four elements as touching those elements around the open slots, just for the sake of making it match nearly all periodic table possibilities. |
