Remembering Dmitri Mendeleev

Dmitri Ivanovich Mendeleev (February 8, 1834-February 2, 1907) was a Russian chemist and inventor.He formulated the Periodic Law, created a farsighted version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.In 1863 there were 56 known elements with a new element being discovered at a rate of approximately one per year. Other scientists had previously identified periodicity of elements.
Mendeleev published his periodic table of all known elements and predicted several new elements to complete the table. For his predicted eight elements, he used the prefixes of eka, dvi, and tri (Sanskrit one, two, three) in their naming. Mendeleev questioned some of the currently accepted atomic weights (they could be measured only with a relatively low accuracy at that time), pointing out that they did not correspond to those suggested by his Periodic Law.The original draft made by Mendeleev would be found years later and published under the name Tentative System of Elements.Russian Academy of Sciences yearly awards since 1998 Mendeleev Golden Medal.
