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.
Another table in order of relative atomic mass. Dmitri Mendeleev (1834 - 1907). In 1869, just five years after John Newlands put forward his law of octaves, a Russian chemist called Dmitri Mendeleev published a periodic table.endeleev also arranged the elements known at the time in order of relative atomic mass relative atomic mass: The relative atomic mass is the number of times heavier an atom is compared to one twelth of a carbon-12 atom.
