!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! PLEASE don't create articles about undiscovered elements unless there is actually something to say about them that is not boilerplate information. Also, please don't link to the articles unless you're going to create them. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! --> An extended periodic table was suggested by Glenn T. Seaborg in 1969 . It is a logical extension of the principles behind the standard Periodic Table to include as-yet-undiscovered Chemical Element s. All of the undiscovered elements are named by the International Union Of Pure And Applied Chemistry (IUPAC) Systematic Element Name standard of creating a generic name until it has been discovered, confirmed and an official name approved. The blue symbol on top of each column shows the placement of each element in each block in the periodic table. It does not always indicate the number of electrons in the orbital (e.g. . Helium is placed next to Hydrogen instead of on top of Neon because it is part of the s2 group. SEE ALSO EXTERNAL LINKS
