Mendeleev was the inventor of the periodic table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence â¦ of elements that had not yet been discovered based on gaps in the table he created.
One thing that Mendeleev did not predict was the discovery of a whole new Group of elements, the noble gases, by the Scot William Ramsay and co-workers during the last decade of the 19 th century (see The discovery of new elements).
