The INTERNET Database of Periodic Tables
There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.
Published by Paneth in 1942 in an article in Nature in which he suggests that newly discovered elements such as Z = 43 should be given names by their discoverers. The other highlighted elements (below) had also not yet been named.
Element 43 had been discovered 9 years earlier but had not been given an official name because there was reluctance to consider synthetic elements on the same footing as naturally occurring ones. This changed as a result of Paneth's article.
