Topic: D. I. Mendeleev
D.I Mendeleev, the great Russian scientist, was born in Tobolsk in 1834. After finishing school at the age of 16 he entered the Pedagogical Institute in Petersburg to study chemistry. In 1855 he graduated from the institute with a gold medal. He was invited to give a course of lectures on theoretical, organic and technological chemistry at Petersburg University. His lectures were always listened to with great interest and attention.
To continue his study and research Mendeleev was sent to Germany in 1859. In 1866 Mendeleev became a professor of chemistry at the University.
The year 1868 was the beginning of his highly important work “Fundamentals of Chemistry”. When working at the subject Mendeleev analyzed an enormous amount of literature, made thousands of experiments and calculations. He made an important observation: he could arrange elements according to a definite system. The result of this tremendous work was the Table of Elements which was published in 1869. Mendeleev was the first to suggest a system of classification in which the elements were arranged in the order of increasing atomic weights. The main idea of the Periodic System is the idea of periodic repetition of properties with the increase of the atomic weights.
Thanks to his investigations Mendeleev was able to predict the existence of unknown elements and their properties.
His Periodic Law opened a new era in the history of chemistry.
