Dimitri Mendelejev
Four elements are not listed, at least not as such. The rest should all be there. For now.
The repeating nature of chemical characteristics of the 92 known elements was systematically ordered in a table by Dimitri Ivanowitch Mendelejev in 1869. Similar attempts were drawn up by J.W. Döbereiner in 1829 and Lothar Meyer in 1868, all long before Niels Bohr developed the atomic theory behind the logical arrangement of the elements.
