The Principles of Chemistry, Volume II

In 1869, a Russian chemist dared to do what no one had attempted: organize all matter in the universe into a single coherent framework. The result was the periodic table, and Volume II of Mendeleyev's monumental work contains the full flowering of that revolutionary insight. Here is the complete account of how one man imposed order on the chaos of the elements, demonstrating that atomic weight determines chemical personality, and that certain elements simply had to exist even though no one had ever seen them. Mendeleev's predictions of gallium, scandium, and germanium read like prophecy fulfilled, and his explanations of isomorphism and crystal chemistry reveal the mind of a thinker operating at the frontier of human knowledge. This is not a textbook. It is a dispatch from the moment chemistry became a science capable of genuine foresight. Reading it, you witness the birth of the modern understanding of matter itself. For anyone curious about where the periodic table came from, or why chemistry works at all, this is the source text: rigorous, ambitious, and startlingly alive.
