This is a book about discovery and disaster, exploitation and invention, warfare and science - and the relationship between human beings and the chemical elements that make up our planet. Lars Ohrstrom introduces us to a variety of elements from S to Pb through tales of ordinary and extraordinary people from around the globe. We meet African dictators controlling vital supplies of uranium; eighteenth-century explorers searching out sources of precious metals; industrial spies stealing the secrets of steel-making. We find out why the Hindenburg airship was tragically filled with hydrogen, not helium; why nail-varnish remover played a key part in World War I; and the real story behind the legend of tin buttons and the downfall of Napoleon. In each chapter, we find out about the distinctive properties of each element and the concepts and principles that have enabled scientists to put it to practical use. These are the fascinating (and sometimes terrifying) stories of chemistry in action.

Pink warships that vanish at dusk, urinary maladies of an emperor, and a gold test for cocaine – behold the chemistry of metal ions as never before.In this book you will learn about the sarcophagus molecule, the Chen-Kao test, and how murderers can be caught blue-handed with the wonders of glowing luminol. You will also meet the hidden chemistry of metal ions in everyday life, from the clever modern devices that measure blood-sugar levels, to the leather on your shoes and chewing gum stuck to their soles.Expect to encounter a fair share of heroes and villains, real and fictional, scientist and layperson. Such characters include an ex-MI5 employee running a hospital ward in London amid falling German V1 rockets, a notorious racing cyclist, a proud butler and the lady who first proposed nuclear fission (it’s not who you think it is).With engaging, humorous and intelligent prose, the reader will discover the fascinating back-stories of chemical discoveries and inventions where metal ions have played a major role.Featuring a foreword by popular science communicator Dr Raychelle Burks of St. Edward's University, Texas.
