The Periodic Table of Science Fiction possibility not normally open to a writer." The print edition was published in 2005, in two signed limited editions: one slipcase hardback edition with a print run of 200, and one hardback edition with a print run of 500 books. In 2009, Swanwick posted the stories on a weblog dedicated to the purpose. The theme of each story in the collection is inspired by the element it is named after. The book also includes an afterword by the author, and a foreword by Theodore Gray who was awarded the IgNobel Prize for Chemistry in 2002. The Periodic Table of Science
Periodic table to oganesson (95–118), occur only when synthesized in laboratories. Of the 94 naturally occurring elements, 83 are primordial and 11 occur only in decay chains of primordial elements. No element heavier than einsteinium (element 99) has ever been observed in macroscopic quantities in its pure form, nor has astatine (element 85); francium (element 87) has been only photographed in the form of light emitted from microscopic quantities (300,000 atoms). A "group" or "family" is a vertical column in the periodic table. Groups usually have more significant periodic trends than periods and blocks, explained below. Modern quantum mechanical theories of atomic
