3.1)The biography of D.I. Mendeleev.

Teacher: Today we are going to have a talk about well-known Russian scientists D. I. Mendeleev. Dmitriy Ivanovich Mendeleev (8 February [O.S. 27 January] 1834 in Tobolsk – 2 February [O.S. 20 January] 1907 in Saint Petersburg), was a Russian chemist. He is credited as being the primary creator of the first version of the periodic table of elements. Unlike other contributors to the table, Mendeleev predicted the properties of elements yet to be discovered.

Mendeleev was born in Tobolsk, Siberia.  his parents was Ivan Pavlovich Mendeleev and Maria Dmitrievna Mendeleeva ( Kornilieva).

Mendeleev was the 13th  child. As a child, he was fascinated by the glass which was created at the factory his mother owned, and for a time, the young Mendeleev worked there. At the age of 13, after the death of his father and the destruction of his mother's factory by fire, Mendeleev attended the Gymnasium in Tobolsk.

In 1849, the now poor Mendeleev family relocated to St. Petersburg, where he entered the Main Pedagogical Institute in 1850. He lived in this house from 1866-1890 and worked in this cabinet.

 In 1862, he married Feozva Nikitichna Leshcheva.

Mendeleev became Professor of Chemistry at the Saint Petersburg Technological Institute. In 1865 he became Doctor of Science for his dissertation "On the Combinations of Water with Alcohol". Though Mendeleev was widely honored by scientific organizations all over Europe, including the Copley Medal from the Royal Society of London he resigned from St. Petersburg University on August 17, 1890.

Mendeleev also investigated the composition of oil fields, and helped to found the first oil refinery in Russia.

Mendeleev died in 1907 in St. Petersburg, Russia from influenza. The Mendeleev crater on the Moon, as well as element number 101, the radioactive mendelevium, are named after him.

He was one of the founders of the Russian chemical Society.

 Teacher: Let’s read a short extract about his achievements. And answer my questions. (просмотровое чтение)

Text№1:

D.I. Mendeleev was also one of the founders of the Russian Chemical Society. In 1869, he made his most renowned contribution to science by postulating the Periodic Law, named after him, and working out the periodic table of elements on the basis of this law. His main work  was focused on various scientific issues, including chemistry, chemical engineering, physics, metrology, aeronautics, meteorology, agriculture, economics and public education. He was also involved in the development of Russian industrial production, settling in Siberia, and mastering the Northern Sea Route. A permanent member of the Council of the Academy of Arts (1894). Mendeleev was buried at Literatorskie Mostky. Element 101 on his periodic table, mendelevium, was named after him. The Mendeleev Congresses on General and Applied Chemistry was established as a tribute to his work. In 1934, the Academy of Sciences of the USSR instituted the Mendeleev Prize, now called the Prize of the Russian Academy of Sciences.

Questions:

1.What was Mendeleev’s contribution to science?

2. What was his main work  focused on?

3. Where was he buried?

4. What element was named after him?

5. Who instituted the Mendeleev Prize? and when?

              3.2) Periodic table.

Teacher: After becoming a teacher, he wrote the definitive two-volume textbook at that time: Principles of Chemistry (1868-1870). As he attempted to classify the elements according to their chemical properties, he noticed patterns that led him to postulate his Periodic Table.

Unknown to Mendeleev, several other scientists had also been working on their own tables of elements.

One was John Newlands, who published his Law of Octaves in 1864. However, the lack of spaces for undiscovered elements and the placing of two elements in one box were criticised and his ideas were not accepted.

Another was Lothar Meyer, who published a work in 1864, describing 28 elements. Like Newlands, Meyer did not seem to have the idea of using a table to predict new elements. In contrast to Newlands' methodical approach to creating a table, Mendeleev's was almost accidental and emerged gradually.

As a better understanding of atomic weights was developed and better data became available, Mendeleev made for himself the following table:

Cl 35.5 K 39 Ca 40
Br 80 Rb 85 Sr 88
I 127 Cs 133 Ba 137

Teacher: Let’s read a short text about “The Periodic table”.(просмотровое чтение)

Text№2

D.I. Mendeleev  developed his version of the periodic table. On March 6, 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence Between the Properties of the Atomic Weights of the Elements, which described elements according to both weight and valence. The arrangement of the elements in groups of elements in the order of their atomic weights, corresponds to their so-called valencies, as well as, to some extent, to their distinctive chemical properties. Only a few months after Mendeleev published his periodic table of all known elements (and predicted several new elements to complete the table), Meyer published a virtually identical table. Some people consider Meyer and Mendeleev the co-creators of the periodic table.

Teacher: Agree or disagree with me.

1.     D.I. Mendeleev  developed his version of the periodic table.

2.     On May 6, 1869, Mendeleev made a formal presentation to the Russian Chemical Society.

3.     The arrangement of the elements in groups of elements in the order of their atomic weights doesn’t correspond to their so-called valencies.

4.     Meyer  predicted several new elements to complete the table.

5.     Some people consider Meyer and Mendeleev the co-creators of the periodic table.

3.3) Other achievements.

Teacher: Mendeleev made other important contributions to Russian chemistry, didn’t he? Do you know, that the Russian chemist and science L.A. Tchugayev has characterized him as "a chemist of genius, first-class physicist, a fruitful researcher in the fields of hydrodynamics, meteorology, geology, certain branches of chemical technology (explosives, petroleum, and fuels, for example) and other disciplines adjacent to chemistry and physics, a thorough expert of chemical industry and industry in general, and an original thinker in the field of economy." Mendeleev was one of the founders, in 1869, of the Russian Chemical Society. He worked on the theory and practice of protectionist trade and on agriculture.
