Mendeleev was born in 1834 in Tobolsk, Siberia, Russia. This era is the period of rapid development of European capitalism. The invention and improvement of science and technology have advanced by leaps and bounds, and chemistry, like other sciences, has made amazing progress. His grandfather was an Orthodox bishop in Tver, and his father graduated from Tver Theological Seminary and later served as the school principal.
/kloc-when he was 0/3 years old, Mendeleev's father died, his mother's factory was destroyed by a fire, and his family's family's family situation plummeted. However, Mendeleev was admitted to Tobolskwenke Middle School, which was also a comfort to his family. 1849, Mendeleev's mother sold her property and took her children to study everywhere, and went to Moscow, Berlin and Paris successively. Finally, she found an opportunity for Mendeleev to study in St. Petersburg Normal School. 1850, Mendeleev studied in the Department of Physical Mathematics.
In September of the same year, Mendeleev's mother died of illness. Mendeleev was determined to study hard and graduated with 1855. However, because he was diagnosed with tuberculosis, he had to go to the Crimean peninsula in the Black Sea to recuperate. During this period, Mendeleev completed his master's degree and returned to St. Petersburg two years later. During this period, I have been to Simferopol and Odessa as middle school teachers. 1857 was hired as a chemistry lecturer by St. Petersburg University.
1869, Mendeleev discovered the periodic law of elements and published the first periodic table of elements in the world. At the same time, according to the order of atomic weight, the elements with similar valence are arranged in columns, and accordingly 12 undiscovered elements are predicted. From 1868 to 1870, he wrote the book Principles of Chemistry, which systematically expounded the basic principles of inorganic chemistry from the viewpoint of periodic law for the first time.

The national metrology research institute of St. Petersburg, which is responsible for national and international precision measurement, is named after Mendeleev. Next to Mendeleev Memorial Hall, there are photos, Mendeleev is seated, and Mendeleev's periodic table is painted on the wall.
The 12th College Building was a normal college in Mendeleev's time, and now it is the center of St. Petersburg State University. There is a Mendeleev Memorial Museum here, and the street in front of it is named Mendeleev Street.
There is a university in Moscow called Mendeleev University of Chemical Technology.
The synthetic chemical element with atomic number 10 1 is also named after Mendeleev. Its English name is mendelevium, abbreviated as Md (formerly Mv), and its Chinese name is Holmium. It is a metallic actinide transuranic element, which is generally prepared by the impact of α particles on polonium atoms.
