Ivanovich Mendeleev

This year marks the 100th anniversary of the death of one of the most famous scientists of all time, the Russian chemist Dmitri Ivanovich Mendeleev (1834-1907). The periodic table that he introduced in 1869 was a monumental achievement— a wonderful mnemonic and a tool that serves to organize the whole of chemistry. No longer were students of chemistry obliged to memorize the properties of all the known elements hereafter they could leam the properties of at least one element from each column and could, in principle, make sound predictions about the other elements in the column. 

This letter, which is held in the Mendeleev archives, is dated February 17, 1869, which is also the date of the famous first table that Mendeleev produced. The letter is from one Alexei Ivanovich Khodnev, secretary of the Free Economic Society in St. Petersburg, inviting Mendeleev to visit a cheese factory where he was due to conduct an inspection. On the back of the letter Mendeleev has made a comparison of the following atomic weights ... 

Is there one best periodic table Many chemists argue that the form of the table is of little importance and that one s choice depends on what particubr aspect of periodicity one wants to depict. But surely this is not the case if. for example, rival versions put helium and hydrogen in radically different places. Such debates will continue for a long time. However, the debate would not exist without Dmitri Ivanovich Mendeleev, and for the very legacy of periodicity we are indebted to him. 

Lars Frederik Nilson (1840-1899) found the element predicted by Dmitry Ivanovich Mendeleev (1834-1907) as "eka-boron" in the mineral gadolinite.

Very soon afterwards, however, two scientists independently produced the definitive statement on the classification of the elements - Julius Lothar Meyer (1830-95) in Germany and Dmitri Ivanovich Mendeleev (1834-1907) (also spelled Mendeleeff or Mendelejeff) in Russia. It is the latter who is now credited with the construction of the first periodic table. At the age of 35, Mendeleev was Professor of Chemistry at the University of St Petersberg, when he published his first paper (1869) on the periodic system. He was apparently unaware of the work of Newlands or Lothar Meyer, but came to the same conclusions, and was also prepared to go further, and predict that certain elements must remain to be discovered because of discrepancies in his table. Amongst other things, he concluded the following ... 

Dmitri Ivanovich Mendeleev was bom in Tobolsk in western Siberia on February 8, 1834. He was of Russian and Mongolian descent, and was the youngest child in a very large family. Some biographers mention seventeen children, but Mendeleev s personal friend Dr. Bohuslav Brauner stated that there were fourteen (37). 

Dmitri Ivanovich Mendeleev, 1834-1907. Professor of chemistry at the University of Fetrograd. Author of the Principles of Chemistry, a remarkable textbook. He studied the important oil fields of Russia and the United States. The periodic system of the elements was discovered independently by Mendeleev in Russia and Lothar Meyer in Germany.

The discovery of the periodic structure of the elements by Dmitri Ivanovich Mendeleev, shown in Fig. 9.1, must be ranked as one the greatest achievements in the history of science. And perhaps the most impressive conceptual accomplishment of quantum mechanics has been its rational account of the origin of the periodic table. Although accurate computations become increasingly more difficult as the number of electrons increases, the general patterns of atomic behavior can be predicted with remarkable accuracy. A modem version of the periodic table is printed on the inside back cover.

Dmitri Ivanovich Mendeleev (1836-1907). Russian chemist. His work on the periodic classification of elements is regarded by many as the most significant achievement in chemistry in the nineteendi century. 

Dimitri Ivanovich Mendeleev s periodic table of the elements has been tremendously important in chemistry and the philosophy of chemistry. It provides a power-fill organizing principle that has led to the discoveries of new unsuspected elements and, until recently, it stands as one of the best examples of a genuinely chemical law. There have been not completely successful—attempts to explain the periodic law with quantum theory (Scerri 2003b), but it remains, like Darwin s theory of natural selection in biology, a cornerstone of chemistry. It would be spectacular if a similar periodic system could be developed for molecules. It would help organizing the massive complexity that constitutes the huge number of known chemical species, and it would help predict new compounds that might be synthesized and developed for practical purposes. It would also be a wonderftd further example of chemistry s...
