…Later, Alexandre Émile Béguyer de Chancourtois (1819-86) of France discovered a new pattern, that is, that when atoms are arranged according to their atomic weight, elements with similar properties appear at almost equal intervals. Based on this, he published an original diagram called the vis de terre (spiral of the earth) in 1862, which arranged elements in a spiral around a cylinder (Figure 1). In addition, JAR Newlands of England published the law of octaves (also called Newlands' law) in 1865, which states that when elements are arranged in order of atomic weight, a similar element appears every eighth element, which is very similar to an octave in music. These were the first steps towards the modern periodic law, but their value was not recognized because of their too original content and novel expression. … *Some of the terminology explanations that refer to "law of octaves" are listed below.

…その後フランスのシャンクルトアAlexandre Émile Béguyer de Chancourtois(1819‐86)は,さらに新しい規則性,すなわち原子を原子量に従って配列していくと,よく似た性質の元素がほぼ等間隔に現れることを発見し,これに基づいて元素を円柱のまわりにらせん状に配列した独創的な図表〈地のらせんvis de terre〉を1862年に発表した(図1)。また,イギリスのJ.A.R.ニューランズは,元素を原子量の順に段階的に配列していくと,8番目ごとによく似た元素が現れ,これが音楽におけるオクターブに酷似しているという〈オクターブの法則law of octaves〉(〈ニューランズの法則〉ともいう)を1865年に発表した。これらは現在の周期律の最初のいとぐちをつかんだものであったが,あまりにも独創的な内容と新奇な表現のため,その価値を認められなかった。… ※「law of octaves」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 |
