Selected facts about D.I. Mendeleev’s life and scientific activity

Dmitri Ivanovich Mendeleev (Figure 1) was born in Siberian town Tobolsk on February 8, 1834. He entered local middle school in 1841 and completed it in 1849. In 1856, he graduated St. Petersburg’s Main Pedagogical Institute (Makarenya, 1982, p. 21). On the January 9, 1857, Mendeleev was employed in the Organic Chemistry Department at the Imperial University in Petersburg as private docent (Zagrebayevaya & Savina, 2014).

In the years 1859 – 1861, he had a fellowship to study in Heidelberg. There he worked in the Laboratory of Robert Wilhelm Bunsen (1811-1899) (Shtrube, 1981/1984, p.77).

In 1860, Mendeleev attended the first ever international chemistry conference held in Karlsruhe (Germany) on 3-5 September (Mendeleev, 1958, pp. 660-669; Mladentsev & Tishchenko, 1938, pp. 243-260). Lecture by Cannizzaro (1826-1910) entitled “The atomic and molecular weights” impressed the participants

Learning Objectives
  • Explain how elements are organized into the periodic table.
  • Describe how some characteristics of elements relate to their positions on the periodic table.

The Periodic Table is the symbol of Chemistry for many. It is a single image that contains all of the known elements in the universe combined into an easily legible table. There are many patterns present in the table as well. All of the elements seem to fit together, connecting to form the "image of chemistry". The idea of elements first came about in 3000 B.C. The great Greek philosopher Aristotle conceived an idea that everything on earth was made up of these elements. In ancient times, elements like gold and silver were readily accessible, however, the elements that Aristotle chose were Earth, Water, Fire, and Air.

Emerging Patterns and Periodicity within the Known Elements

The modern periodic table has evolved through a long history of attempts by chemists to arrange the elements according to their properties, as

How Sanskrit Led To The Creation Of Mendeleev’s Periodic Table

How the two-dimensional structure of Sanskrit could have led to the creation of the periodic table.

It is an amusing fact that the original names used by Mendeleev for gallium and germanium are eka-aluminum and eka-silicon, where the eka, Sanskrit for one, has the sense of beyond. The prediction for the existence of these elements was made by Mendeleev in a paper in 1869, and it was the identification of these elements in 1875 and 1886 that made him famous, and led to the general acceptance of the periodic table. In all, Mendeleev gave Sanskrit names to eight elements in his periodic table. Here we speak of how the two-dimensional structure of Sanskrit led him to his momentous discovery.

Mendeleev was born at Tobolsk, Siberia, and educated in St. Petersburg. He was appointed to a professorship in St. Petersburg 1863 and in 1866 he succeeded to the Chair of Chemistry in the University. He is best known for his work on the periodic table, which was soon recognized since he predicted the existence and
