În același an, în jurnalul Societății apare o versiune completată a tabelului, care va fi însoțită și de un scurt rezumat în limba germană. Dmitri Ivanovich Mendeleev was not the first to recognize the periodicity of the chemical elements or even to construct a primitive periodic table. He was also skeptical of the noble gases when they were discovered in the 1890s because they did not form bonds with other elements and so had no place in his table. A further reason for Mendeleev's greater priority is due to the fact that Lothar Meyer was working in a highly formal German Chemical Society which discouraged speculations. mendeleev offers also methods for accessing whole tables of data, e.elbat cidoirep eht fo rednuof eht retfa muivelednem deman si ,5591 ni dezisehtnys ,101 rebmun tnemelE .
