Who is Dmitry Ivanovich Mendeleev?June 25, 2021
Dmitry Ivanovich is a Russian scientist.
The youngest of his family’s 17 children, Mendeleev’s grandfather was publishing Siberia’s first newspaper; His father was a high school principal. Mendeleev did his primary education in exile; When his father died, his mother immigrated to the west to provide him with better educational conditions.
Mendeleev, St. Petersburg (Leningrad) University and did his doctorate on the interesting topic “The combination of alcohol and water”. His studies in France and Germany enabled him to attend the 1858 Karlsruhe Chemistry Conference. There were heated debates on the Avogadro Hypothesis at this conference. He then toured the oil fields in Pennsylvania to see the first oil well. After returning to Russia, he developed a new method of commercial distillation.
At the age of 32, St. He became a professor of chemistry at St. Petersburg University. To search for regularities, he ordered the elements according to their properties. Thus, he obtained the periodic table, the silent computer of chemists. Based on this table, he predicted that some elements that were not yet known at that time would be found and some of their properties.
The importance of the periodic table was realized when some of the elements he reported were found a few years later, and Mendeleev became known as a great scholar.
The periodic table is a striking product of Mendeleev’s excellent interpretation and productive intelligence. Other works of Mendeleev consisting of 25 great books are also quite interesting. His organization of knowledge about isomorphism led to the development of geochemistry. He was also known as a great physical chemist because he found the critical boiling point and developed the hydrate theory of solutions. Mendeleev was a member of about 70 academic and scientific societies. In his own words, his first service was scientific research and the second was teaching.
This tireless experimenter and teacher was also concerned with social issues. In order not to interfere in the affairs of the government, he found it appropriate to resign from the professorship rather than to listen to the order. He supported liberal ideas, refused to cut his hair, and opposed the Tsar’s wishes. Despite this, he was appointed to the “Bureau of Weights and Measures” director. When Mendeleev published the first periodic table, 63 elements were known. One year after his death, the number of known elements had increased to 86. This rapid increase was achieved through the periodic table, which is the most important generalization of chemistry.
The element with atomic number 101, synthesized in 1955 by US physicists led by Glenn Seaborg, was named “mendelevium” in honor of Dimitri Mendeleev. Who is Mendeleev?
