Although Gordin explains that mass was Mendeleev's basis for ordering the elements in the periodic table, he barely mentions that the modern periodic table is ordered by atomic number--the number of protons in the nucleus. In his conclusion, Gordin depicts Mendeleev as a combination of a painting and a statue.
