About the Program: A Tale of Seven Elements, presented by Eric Scerri

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 lineup–seven elements unknown to science.

In his well-researched and engaging 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 with the isolation of protactinium in 1917 and ending with that of promethium in 1945.
