Dmitri Mendeleev was born in 1834. In Tobolsk. He was the last, probably seventeenth child in the family. Known for his discovery of the law of periodicity of chemical elements. It was a turning point in the development of chemistry, which gave the opportunity to predict the properties of elements yet undiscovered.

The most famous work of the Russian chemist is the periodic table of elements, or Mendeleyev's table. This is a summary of all the chemical elements in order of their increasing atomic number. The basis of the array is the right periodicity of the Mendeleev. In 1869. Chemist found that the properties of elements are dependent on their atomic masses and on this basis it grouped the table. In the same year he published the first periodic table that contains more than 90 elements.

Dmitri Mendeleev was born on 8 February 1834. In Tobolsk in the family Decembrist Ivan Mendeleev, who was then director of the school, and Maria Mendeleev, the owner of the glass factory. Most likely he was seventeen (some sources say that the fourteenth), the youngest child in the family.

At the age of 13 years Dmitry lost his father. A year later he burned belonging to the mother plant. Then Maria Mendeleev decided to move to St. Petersburg. She noted that her youngest son has a special ability to learn, and she wanted received higher education.

After graduation, Mendeleev worked as a teacher and later as a lecturer at the University of St. Petersburg. However, in 1890. In the development of a scientific career prevented him liberal views. When interceded for students demands to liberalize the system of government Minister of Education sanctioned him with a reprimand. After this event, Mendeleev left the university.

World Scientific highly of the work of the Russian chemist. In 1905. Mendeleev was elected to the Royal Swedish Academy of Sciences, and a year later he was nominated for the Nobel Prize for the discovery of the periodic table. Conclusion supported the section Chemical Academy, which was almost tantamount to awarding prizes. But eventually, under pressure Svantego Arrhenius, a Swedish chemist known, prize Frenchman Henri Moissan. There were rumors that the Arrhenius guided jealousy and revenge for criticism of Mendeleyev about his theory of electrolytic dissociation.

The great chemist, died in St. Petersburg in 1907. Pneumonia. He was 72 years old. He left 1.5 thousand. wash.
