Description: In 1913, English physicist Henry Moseley established an elegant method for ""counting"" the elements based on atomic number, ranging them from hydrogen (#1) to uranium (#92). It soon became clear, however, that seven elements were mysteriously missing from the line up--seven elements unknown to science. In his well researched and engagingly narrative, Eric Scerri presents the intriguing stories of these seven elements--protactinium, hafnium, rhenium, technetium, francium, astatine and promethium. The book follows the historical order of discovery, roughly spanning the two world wars, beginning.
Notes: Includes bibliographical references (pages 209-244) and indexes.
