…In the process, he regarded elements as abstract concepts with common properties of simple substances and compounds, and, unlike his predecessors, he made a clear and conscious distinction between elements and simple substances. In the process of writing his major work, the chemistry textbook Principles of Chemistry (1868-71), he realized that the atomic weight, an invariant quantity belonging to these elements, made it possible to make comprehensive comparisons between dissimilar element families, and he discovered the periodic law (March 1869), which states that the properties of elements are periodic functions of atomic weight. For the next three years, he concentrated on research into the element system based on the periodic law, and after making detailed predictions of the properties of unknown elements in 1870, he published a nearly 100-page summary paper in a German journal in 1871. … *Some of the terminology explanations that refer to "Principles of Chemistry" are listed below.

…その過程で元素を単体・化合物の共通な性質の抽象概念としてとらえ,先行者と異なり,元素と単体をはっきり意識的に区別した。彼の主著である化学教科書《化学の原理》(1868‐71)の執筆過程で,こうした元素に属する不変量である原子量によって,似ていない元素族の包括的な比較が可能であることに気づき,〈元素の性質は原子量の周期関数である〉とする周期律発見に至った(1869年3月)。続く3年間は,周期律に基づく元素体系研究に集中し,70年の未知元素の性質の詳細な予言を経,71年に100ページ近くの総括論文をドイツの雑誌に発表した。… ※「《化学の原理》」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
