PDF | This note presents reasons why Mendeleev chose Sanskrit names (now superseded) for eight elements in the periodic table. The periodic table of elements, available as both a full color, grayscale, or a black -and-white pdf document.
Eventually, his predictions proved to be correct. Not only did he mail his table to colleagues in Western Europe, in , he visited chemistry hubs in order to inform his colleagues first hand about his periodic table.
During these months and years he kept improving his table. Simultaneity of the discovery As it often happens with significant discoveries for which the time had become ripe, several scientists more or less about the same time came to the conclusion of periodicity in the system of the chemical elements.
The best known of them were Lothar J.
Meyer — in Germany and John A. Newlands — in England. Newlands did not fare well in his home territory and he did not expose his discovery internationally. When he revealed his observation of periodicity in the properties of the elements, some of his colleagues ridiculed him—it was so alien to them to absorb his revolutionary idea.
Someone even asked him whether he had tried to classify the elements according to the initial letters of their names. Newlands also made predictions for elements not yet known, but his ideas did not meet interest or approval. His accounts reflect his justified bitterness [ 3 ]. No prophet in his own country Considering the milestone significance of the discovery of the Periodic Table of the Elements, there is scarce remembrance of Newlands and Lothar Meyer.
Newlands, —, chemist and discoverer of the Periodic Law for the chemical elements, was born and raised here. The Italian chemist Stanislao Cannizzaro — made seminal contribution to the discovery of the Periodic Table providing the most accurate atomic weights at the time.
Mendeleev was not spoiled by recognition in Russia during his lifetime. Subsequently, however, he lost his professorships ostensibly because of his support of the student movements aiming at improving their conditions of life and studies.
He was elected a corresponding member of the Russian Academy of Sciences in , but in , he was voted down when his full membership was being decided. This happened in spite of his international fame and his having made Saint Petersburg and international hub of chemistry. Ostensibly, the controversy of his second marriage, which took place some time before his divorce from his first wife, contributed to his negative treatment by the Academy. This was a conspicuous humiliation as the full membership is so much more important than being a corresponding member in the two-tier system of the Russian Academy of Sciences.
Although the Nobel Prize is supposed to be awarded for recent discoveries, it was argued successfully that the Periodic Table of the Elements gained added significance recently. In , the top nominees were the German organic chemist Adolf von Baeyer and the French inorganic chemist Henri Moissan in addition to Mendeleev and the prize was awarded to von Baeyer.
In , the Nobel Committee of Chemistry recommended Mendeleev for the prize to the general meeting of the prize-awarding body, the Royal Swedish Academy of Sciences.
The vote in the committee was by a majority. The single dissent vote went for Moissan. The dissenting member of the committee, Peter Klason, argued forcefully for Moisson. This was a reasonable stipulation, but the inclusion of Cannizzaro was not possible in because only those for whom nominations had been made by January 31 could be considered. Cannizzaro was not among the nominees in According to the decision by the Royal Swedish Academy, in , the prize went to Moisson.
In , both Mendeleev and Cannizzaro were among the nominees, but Mendeleev died early in the year and the rules of the Nobel Prize exclude posthumous awards. It is the institution of the Nobel Prize that suffers from his absence from among its awardees. Todd Helmenstine Here is the pdf file of the color periodic table so you can save and print it.
