This photo shows how I interpreted the elements that have temporary names. That means that most of them have been "discovered" (synthesized) but IUPAC and IUPAP have not verified them or agreed on a two-letter symbol and name. Note that UUS, (atomic number 117) has not been discovered yet.The layout of the three-letter elements is not ideal, but I was happy just to get three letters squeezed into the space originally intended for two letters. As the new elements get permanent names, I have the option of changing the letters. I might also be too lazy to do that.
