The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today. [citation needed] Mendeleev arranged the elements by atomic mass, corresponding to relative molar mass.
1 Once again, the elements were arranged in order of increasing atomic weights. 2  Also in 1869, Russian chemist Dmitri Mendeleev produced a periodic table based on atomic weights but arranged âperiodicallyâ. 3  Elements with similar properties appeared under each other. Certain âthreesâ of elements with similar properties came together down the cylinder. 2  He called his model the âtelluric screwâ. 3  In 1864, English chemist John Newlands noticed that, if the elements were arranged in order of atomic weight, there was a periodic similarity every 8 elements.
