In the mid-nineteenth century, chemists came to the conclusion that elements should be organized by their atomic weights. However, the atomic weights of various elements were calculated erroneously, and chemists also observed some anomalies in the properties of other elements. Over time, it became clear that the periodic table as currently comprised contained gaps, missing elements that had yet to be discovered. A rush to discover these missing pieces followed, and aseemingly endless amount of elemental discoveries were proclaimed and brought into laboratories. It wasn't until the discovery of the atomic number in 1913 that chemists were able to begin making sense of what did and what did not belong on the periodic table, but even then, the discovery ofradioactivity convoluted the definition of an element further. Throughout its formation, the periodic table has seen false entries, good-faith errors, retractions, and dead ends; in fact, there have been more elemental "discoveries" that have proven false than there are current elements on the table.The Lost Elements: The Shadow Side of Discovery collects the most notable of these instances, stretching from the nineteenth century to the present. The book tells the story of how scientists have come to understand elements, by discussing the failed theories and false discoveries that shaped the path of scientific progress. Chapters range from early chemists' stubborn refusal to disregard alchemy as legitimate practice, to the effects of the atomic number on discovery, to the switchin influence from chemists to physicists, as elements began to be artificially created in the twentieth century. Along the way, Fontani, Costa, and Orna introduce us to the key figures in the development of the periodic table as we know it. And we learn, in the end, that this development was shaped by errorsand gaffs as much as by correct assumptions and scientific conclusions.

Recenzii

Recommended. All academic, general, and professional history of chemistry collections.
Rarely has so much been written so authoritatively about things that do not exist. In their marvellous The Lost Elements, chemists Marco Fontani, Mariagrazia Costa and Mary Virginia Orna detail the discovery of dozens of elements that turned out not to be ... staggeringly comprehensive, well researched book
Thank goodness these stories have been brought back to life.
This reasonably-priced book has excellent indexes of discoverers' names, the lost elements (preceded by a chronological list of these) and general subjects. The literature coverage is heroic, with 1500 up-to-date references, often from obscure journals.
The book is meticulously researched and fills a void in the history of chemistry ... A valuable reference for historians of science and an essential read for anyone with a serious interest in the elements and their discovery.
The Lost Elements: The Periodic Tables Shadow Side is a book to be savored, read and reread, because it reveals the real history of chemistry in the form of adventure stories.
