UNIT 6.
D. I. MENDELEEV
D.I. Mendeleyev, the great Russian chemist, was born in Siberia in Tobolsk in 1834. At the age of 7 he went to gymnasium at Tobolsk. He studied very hard and especially liked mathematics, physics and history. At the age of 17 he entered the Pedagogical Institute in Petersburg, physico-mathematical department.
He graduated from the Institute in 1855 and began to teach chemistry at the Technological Institute and then at the University. In 1867 Mendeleyev delivered lectures on theoretical, organic and technological chemistry. His lectures were a great success. Students from other faculties came to listen to him. Besides lectures Mendeleyev carried on great research work.

Mendeleyevs greatest discovery was the Periodic Law. While studying different elements Mendeleyev made an important observation: he could arrange elements according to a definite system.
In 1869 Mendeleyev published his Principles of Chemistry. The Periodic Law suggested by Mendeleyev stated that the properties of the elements were a periodic function of their atomic masses. His periodic Law opened a new era in the history of chemistry. Mendeleyev wrote over 350 scientific works. His works dealt with many subjects: properties of liquids, theories of solutions, the development of the gas law, the use of oil and many others.
He did much for the development of coal, petroleum and steel industries in Russia. D.I. Mendeleyev continued his research work to the very last day of his life.He died in 1907. But up to the present time scientist use Mendeleyevs Periodic Law in their scientific work.

ANTOINE LAVOISIER
There were several figures in chemistry who had greatly transformed the science of chemistry by their own contribution. Undoubtedly we consider Antoine Lavosier to be one of them. Lavoisier was called the The Father of Modern Chemistry.
Antoine Lavoisier was born in the family of a Paris Parliament prosecutor in 1743. He showed his remarkable and extraordinary abilities in science from his childhood. Lavoisier was splendidly educated. In 1764 Lavoisier graduated from the Law Faculty of Paris University but simultaneously he worked in natural sciences, especially in physics and chemistry. At the age of 23 he was awarded a medal by the Academy of Sciences for a paper on the lighting of a large town. In 1772 Lavoisier became a member of the Academy of Sciences and its Director in 1785.
He was practically the first to introduce quantitative methods in chemical investigations but it was not the only thing he had done. His interests in chemistry were very wide. He worked at the problems of oxidation, he proved the significance of carbon dioxide in the process of breathing.
Lavoisier proved that air was not a chemical compound but a mixture. He was the first to demonstrate that no weight is gained or lost in a chemical change, a fact that we have referred to as the law of conservation of matter. Lavoisier was also a good businessman. His business operations gave him a lot of money, a small part of it being enough for all his scientific experiments.
Antoine Lavoisier was a politician as well. During the French Bourgeois Revolution he supported the adherents of constitutional monarchy. Later he was put before the court and executed in 1793.
