Paperback. Etat : New. Print on Demand. This book examines the periodic relationships between the properties of the chemical elements and their atomic weights. By arranging the elements in vertical groups in order of increasing atomic weight, the author finds that elements with similar chemical properties tend to fall in horizontal rows. This book argues that the properties of an element are to some extent determined by its atomic weight. A system is proposed in which each element is given a position based on its atomic weight; this arrangement reveals patterns and regularities among the elements. The author also discusses how these relationships can be used to predict the properties of new elements that have yet to be discovered. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

(21 x 14 cm). (2) X, 652 S. Mit 6 gefalteten lithographierten Tafeln und 1 gefalteten Tabelle. Pappband der Zeit. Erste deutsche Ausgabe von Mendelejeffs Doktorarbeit. "In it he first developed the characteristic view that solutions are chemical compounds and that dissolving one substance in another is not to be distinguished from other forms of chemical combination. In this thesis, he also adhered to the principles of chemical atomism" (DSB). - Exlibris. Stempel auf Titel. Vorderer Vorsatz mit keinem Einriß, sonst gut erhalten. - DSB 9, 286.…

(25 x 20,5 cm). 1450 S. Halbleinwandband der Zeit. Erste Ausgabe dieser bedeutenden Arbeit, die zur Bestätigung des Mendelejeffschen Periodensystems beiträgt indem das neu entdeckte Element Gallium den bis dahin leeren Platz im Periodensystem zwischen Aluminium und Indium einnimmt. - "The discovery of the three elements predicted by Mendeleev was, however, of decisive importance in the acceptance of his law. In 1875 Lecoq de Boisbaudran, knowing nothing of Mendeleev's work, discovered by spectroscopic methods a new metal, which he named gallium. Both in the nature of its discovery and in a number of its properties gallium coincided with Mendeleev's prediction for eka-aluminum, but its specific weight at first seemed to be less than predicted. Hearing of the discovery, Mendeleev sent to France 'Zametka po povodu otkrytia gallia' ('Note on the Occasion of the Discovery of Gallium'), in which he insisted that gallium was in fact his eka-aluminum. Although Lecoq de Boisbaudran objected to this interpretation, he made a second determination of the specific weight of gallium and confirmed that such was indeed the case. From that moment the periodic law was no longer a mere hypothesis, and the scientific world was astounded to note that Mendeleev, the theorist, had seen the properties of a new element more clearly than the chemist who had empirically discovered it. From this time, too, Mendeleev's work came to be more widely known" (DSB). - Vereinzelt etwas stockfleckig. Oberes Kapital etwas bestoßen, sonst gut erhalten. - DSB 9, 286.…

Library ink stamp half title page, no other library markings. Age darkening pages. No title page present. 8vo. Hardcover. Very Good++.A number of other chemists specializing in the system of the elements either attacked Mendeleev's law or disputed his priority. Lothar Meyer, for example, proposed in 1870 a representation for the atomi volumes of the elements in the form of a broken zigzag line. Blomstrand and E. H. von Blomhauer developed a spiral system, also in 1870. Mendeleev answered these and other claims to the periodic law-and also claims against it - in the article "K Voprosu O Sisteme Elementov" ("Toward the Question of a System of Elements"), published in March 1871. Basically, however, he had no patience with disputes over priority, and although by taste an internationalist in science, he engaged in such disputes only when others denigrated Russian achievements.
