Quotes by Dmitri Mendeleev

“Sandro was surprised when I tried to explain to him some of the ideas that at the time I was confusedly cultivating. That the nobility of man, acquired in a hundred centuries of trial and error, la...”

“In writing a textbook of general chemistry, Mendeleev devoted separate chapters to families of elements with similar properties, including the alkali metals, the alkaline earth metals, and the halo...”

“Mendeleev noticed that there were regular repeating patterns and similarities between different elements when they were ordered in terms of their atomic weights. Atomic weight was originally calcul...”

“Despite Mendeleev's initial system being flawed, and the correct theoretical basis of the periodic table not being identified for another 50 years, Mendeleev was able to predict correctly a number ...”

“Germanium, which name you should preserve since you are factually its father, is the element eka-silicon, Es-73, predicted by Mendeleev, the lowest homolog of tin, standing in the first large perio...”

“Dimitri was writing a textbook and wanted to organize the elements properly. So he wrote each element onto its own card to help him sort them out. Dimitri enjoyed playing cards, especially patience...”

“Mendeleev... set about writing a book aimed at summarizing all of inorganic chemistry. It was while writing this book that he identified the organizing principle... the periodic system of the eleme...”

“Dimitri Mendeleev was probably the greatest scientist produced by Russia. ...the periodic table was developed by Mendeleev, as well as five other scientists, over a period of about 10 years, after ...”

“The table of Mendeleeff was changed but little for thirty years. Its anomalies, as the omission of hydrogen and the rejection of the atomic weight as the deciding factor in such cases as cobalt and...”

“The work of Mendeleev has lately thrown a new light upon the relations existing between the atomic weights of the elements and their properties. The latter are a function of the atomic weight, whic...”

“He formulated, as the fundamental law of the physico-chemical sciences, the dictum that all the properties of bodies are periodic functions of their atomic weights... on reaching this point of its ...”
