In 1869, his colleague nikolai menshutkin on the behalf of mendeleev presented the paper the dependence between the properties of the atomic weights of the elements to the russian chemical society.
Before mendeleev, religion and beliefs shaped people's choices rather than science and facts. Modern day periodic tables are expanded beyond mendeleev's initial 63 elements. Mid molar masses of elements were known. Dmitri mendeleev, russian chemist who devised the periodic table of the elements. What is truly extraordinary about this work is that the scientist predicted the existence of certain the properties of these elements were surprisingly similar to those described by dmitri mendeleev earlier, which left no doubts about the importance of.
