The greatness of Mendeleev was that not only did he leave spaces for elements that were not yet discovered but he predicted properties of five of these elements and their compounds. How foolish he would have seemed if these predictions had been incorrect but fortunately for him three of these missing elements were discovered by others within 15 years (ie within his lifetime).
Dmitri Mendeleev was a famous Russian chemist and inventor who formulated Periodic Law and created his own version of the Periodic Table of Elements.He used the table to correct properties of some discovered elements and to predict elements that were yet to be discovered.mitri Mendeleevâs greatest achievement was the Periodic Table. He always felt that there was some time of order to the elements. He actually spent more than 13 years of his life working on this periodic table. He collected data and assembled the concept with the idea of resolving the disorder in this table.
