Certainly the periodic tables we had when I was in senior secondary school (late 80s) had the elements beyond 103 unnamed, because no-one could agree on the names at that stage.
Yeah those tables were still hanging out in highschools in Canberra. There's also the "unun" series, which were placeholder names made by IUPAC, until the credit for discovery was made official. But this time the two warring parties just started pumping out their own names. Come on guys. You made like, probably a dozen atoms, and they wouldn't have lasted more than a few microseconds.
