In "The Story of Alchemy and the Beginnings of Chemistry" (1902) M. M. Pattison Muir reveals the history of Chemistry from the old Greek thinkers until his own age, the end of the 19th century. Excerpt: "'The Story of Alchemy and the Beginnings of Chemistry' is very interesting in itself. It is also a pregnant example of the contrast between the scientific and the emotional methods of regarding nature; and it admirably illustrates the differences between well-grounded, suggestive, hypotheses, and baseless speculations."

Join world-leading scientists as they delve into the incredible stories behind 16 elements, including the dark and controversial history of gold; how a solar eclipse in 1868 led to the discovery of the periodic table's most notorious escape artist, helium; the role of iron in the rise and fall of human civilisations; why you might find iodine in British milk, but not necessarily anywhere else in the world; and how a discovery in boiled urine led to the trade union movement and a chemical weapon.

Each day we are exposed to a myriad of natural and human-made chemicals in our food, drinking water, air, soil, at home or at the workplace-pesticide residues, food additives, drugs, household products-but how can we gauge the human health risk posed by these chemicals? Should we believe the somber headlines that depict a serious threat for humans and the environment, or should we follow the reassuring voices of others who claim that the angst is totally unfounded?

Before there even was modern era medications and its pharmacopoeia of artificial medications, there were medicinal plants. Prehistoric civilizations have widely used them for the strategic treatment of common illnesses as well as life-threatening ailments. More recently, the information about medicinal plants was handed over from one generation to the next.

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. For each element, Scerri traces the research that preceded the discovery, the pivotal experiments, the personalities of the chemists involved, the chemical nature of the new element, and its applications in science and technology.

From fire to fallout, potions to polymers — this is the story of how we figured out what everything is made of. Chemistry 101 isn’t your high school textbook. It’s a walkthrough of how humans turned mystery into mastery. You’ll meet alchemists chasing gold, scientists splitting atoms, and modern chemists designing synthetic realities out of carbon and code. Packed with stories, structure, and the messy human drive to mix, burn, and bottle the universe, this book walks you through the wild history of reactions — from ancient smelting pits to lab-grown meat and CRISPR edits.

It is the second book in the series of basic chemistry. First book deals with some elementary concepts like from what the matter around us made up of? Why some substances react and some not? In this book we will try to explore, actually what happens when these substances react? What are the factors which govern these reactions? We shall also perceive the properties of these substances. For our convenience we will categories the substances as acid, base, salt, metal, non-metal and carbon compounds. In the last chapter our emphasis will be at the classification of elements.
