Русский: Д. И. Менделеев, 1855

Dmitri Mendeleev was a Russian chemist and inventor who is best known for his development of the periodic table of elements. He was born on 1834, in Tobolsk, Siberia, and died on 1907, in St. Petersburg, Russia. Mendeleev's most significant contribution to science was his creation of the periodic table, which he published in 1869. He arranged the elements based on their atomic mass and observed patterns in their chemical properties. He left gaps in the table for elements that had not yet been discovered, accurately predicting their properties. This allowed for the prediction of new elements and their properties, some of which were discovered years later and matched Mendeleev's predictions. In addition to his work on the periodic table, Mendeleev made several other important contributions to chemistry. He developed a system for naming organic compounds, known as the nomenclature system, which is still widely used today. He also conducted extensive research on the properties of gases and their behavior under different conditions. Mendeleev's work had a profound impact on the field of chemistry and laid the foundation for our understanding of the elements and their properties. His periodic table became a fundamental tool for chemists and remains a cornerstone of modern chemistry. Mendeleev's legacy as one of the greatest scientists in history is widely recognized, and his contributions continue to be celebrated and studied to this day.
