The lost elements

"Throughout its formation, the periodic table of elements has seen false entries, good-faith errors, retractions, and dead ends. In fact, there have been more falsely proclaimed elemental discoveries throughout history than there are elements on the table ... The Lost Elements: The Periodic Table's Shadow Side collects the most notable of these instances, stretching from the nineteenth century to the present [and] ... 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"--Barnes and Noble.
