In March 1869, Mendeleev delivered a full paper to the Russian Chemical Society spelling out the most significant aspect of his system, that characteristics of the elements recur at a periodic interval as a function of their atomic weight. Mendeleev carried on many other activities outside academic research and teaching. He recognized the relationship between atomic mass and other elemental properties needed for their comprehensive organization. Cool online chemistry videos, dictionary, tools, etc. By ordering the elements according to increasing atomic weight in vertical rows so that the horizontal rows contain analogous elements,still ordered by increasing atomic weight, one obtains the following arrangement, from which a few general conclusions may be derived. 11 January 2019 Dmitri Mendeleev is known as the father of the periodic table, but his interests were wide-ranging and sometimes eccentric.
