By the English chemist whose work on the atomic weights of the elements anticipated the periodic table of Mendeleev, and who predicted the element germanium before its discovery by the latter.
By the dawn of the nineteenth century, "elements" had been defined as basic building blocks of nature resistant to decomposition by chemical means. In 1869, the Russian chemist Dmitri Ivanovich Mendeleev organized the discord of the elements into the periodic table, assigning each element to a row, with each row corresponding to an elemental category. The underlying order of matter, hitherto only dimly perceived, was suddenly clearly revealed. This is the first English-language collection of Mendeleev's most important writings on the periodic law. Thirteen papers and essays, divided into three groups, reflect the period corresponding to the initial establishment of the periodic law (three papers: 1869-71), a period of priority disputes and experimental confirmations (five papers: 1871-86), and a final period of general acceptance for the law and increasing international recognition for Mendeleev (five papers: 1887-1905). A single, easily accessible source for Mendeleev's principle papers, this volume offers a history of the development of the periodic law, written by the law's own founder.

As 2019 has been declared the International Year of the Periodic Table, it is appropriate that Structure and Bonding marks this anniversary with two special volumes. In 1869 Dmitri Ivanovitch Mendeleev first proposed his periodic table of the elements. He is given the major credit for proposing the conceptual framework used by chemists to systematically inter-relate the chemical properties of the elements. However, the concept of periodicity evolved in distinct stages and was the culmination of work by other chemists over several decades. For example, Newland’s Law of Octaves marked an important step in the evolution of the periodic system since it represented the first clear statement that the properties of the elements repeated after intervals of 8. Mendeleev’s predictions demonstrated in an impressive manner how the periodic table could be used to predict the occurrence and properties of new elements. Not all of his many predictions proved to be valid, but the discovery of scandium, gallium and germanium represented sufficient vindication of its utility and they cemented its enduring influence. Mendeleev’s periodic table was based on the atomic weights of the elements and it was another 50 years before Moseley established that it was the atomic number of the elements, that was the fundamental parameter and this led to the prediction of further elements. Some have suggested that the periodic table is one of the most fruitful ideas in modern science and that it is comparable to Darwin’s theory of evolution by natural selection, proposed at approximately the same time. There is no doubt that the periodic table occupies a central position in chemistry. In its modern form it is reproduced in most undergraduate inorganic textbooks and is present in almost every chemistry lecture room and classroom. This first volume provides chemists with an account of the historical development of the Periodic Table and an overview of how the Periodic Table has evolved over the last 150 years. It also illustrates how it has guided the research programmes of some distinguished chemists.
Leads the reader on a delightful and absorbing journey through the ages, on the trail of the elements of the Periodic Table as we know them today. He introduces the young reader to people like Von Helmont, Boyle, Stahl, Priestly, Cavendish, Lavoisier, and many others, all incredibly diverse in personality and approach, who have laid the groundwork for a search that is still unfolding to this day. The first part of Wiker's witty and solidly instructive presentation is most suitable to middle school age, while the later chapters are designed for ages 12-13 and up, with a final chapter somewhat more advanced. Illustrated by Jeanne Bendick and Ted Schluenderfritz.

Eric R. Scerri presents a modern and fresh exploration of this fundamental topic in the physical sciences, considering the deeper implications of the arrangements of the table to atomic physics and quantum mechanics. This new edition celebrates the completion of the 7th period of the table, with the naming of elements 113, 115, 117, and 118
The story of the false entries, good-faith errors, retractions, and mistakes that occurred during the formation of the Periodic Table of Elements as we know it.
In a relatively brief but masterful recounting, Professor Ulf Lagerkvist traces the origins and seminal developments in the field of chemistry, highlighting the discoveries and personalities of the individuals who transformed the ancient myths of the Greeks, the musings of the alchemists, the mystique of phlogiston into the realities and the laws governing the properties and behavior of the elements; in short, how chemistry became a true science. A centerpiece of this historical journey was the triumph by Dmitri Mendeleev who conceived the Periodic Law of the Elements, the relation between the properties of the elements and their atomic weights but more precisely their atomic number. Aside from providing order to the elements known at the time, the law predicted the existence and atomic order of elements not then known but were discovered soon after.An underlying but explicit intent of Lagerkvist's survey is to address what he believes was a gross injustice in denying Mendeleev the Nobel Prize in Chemistry in 1905 and again in 1906. Delving into the Royal Swedish Academy of Sciences' detailed records concerning the nominations, Lagerkvist reveals the judging criteria and the often heated and prejudicial arguments favoring and demeaning the contributions of the competing contenders of those years. Lagerkvist, who was a member of the Swedish Academy of Sciences and has participated in judging nominations for the chemistry prize, concludes "It is in the nature of the Nobel Prize that there will always be a number candidates who obviously deserve to be rewarded but never get the accolade" -- Mendeleev was one of those.
