…These discoveries were followed by the discovery of the triad of elements Triaden by J. W. Dobereiner (1827), the establishment of a method for determining atomic weights (1860), and the discovery of the periodic law (1869), which organized the elements by arranging them in order of atomic weight (see the entries Periodic Table and Periodic Law). In 1958, A. S. Ahrland and others from Sweden proposed a new systematic classification method for metal ions based on the stability constants of metal complexes. According to this, metal ions are classified into the following two types based on the magnitude of the stability constants, which depend on the type of coordination atom in the complex they form. … *Some of the terminology explanations that mention "Arland, SH" are listed below.

…これらの発見に続いて,J.W.デーベライナーによる三つ組元素Triadenの発見(1827),原子量決定法の確立(1860)を経て,元素を原子量順に配列することによる系統化をもたらした周期律の発見(1869)が行われた(〈周期表〉〈周期律〉の項参照)。 1958年スウェーデンのアールランドS.H.Ahrlandらは,金属錯体の安定度定数をもとにした金属イオンの新しい系統的分類法を提唱した。これによると金属イオンは,それがつくる錯体の配位原子の種類による安定度定数の大小から次の2種類に分類される。… ※「アールランド,S.H.」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 |
