The Holleman/Wiberg has been providing comprehensive knowledge of inorganic and organometallic chemistry for decades. With the 103rd edition, a new work has emerged following extensive restructuring of the previous edition, designed for thorough exam preparation and as a reference work. Additional areas of chemistry and current chemical facts are documented in new chapters, tables, figures, and formula images. All chapters addressing the molecular, solid-state, organometallic, bioinorganic, technical, and nuclear chemistry of the 114 known elements have been updated to the latest scientific standards. The two volumes are also available as supplementary group elements, lanthanides, actinides, transactinides, and appendices.
