…Carbon has a medium electronegativity of 2.5, and in addition to bonding with metals or metallic elements to form carbides, it also produces inorganic compounds such as carbon dioxide, carbon disulfide, carbon tetrachloride, and various carbonates, but its most distinctive feature is that it forms a huge number of different organic compounds. This is because carbon is the most typical nonmetallic element, and it exhibits the phenomenon of catenation, in which atoms of the same element bond together in a chain. This tendency is strongest among all elements for carbon, and generally occurs less frequently the further an element is from carbon in the periodic table. … *Some terminology explanations that mention "catenation" are listed below.

…炭素の電気陰性度は2.5で中程度の値をもち,金属ないし金属性元素と結合し,炭化物をつくるほか,二酸化炭素,二硫化炭素,四塩化炭素,各種炭酸塩などの無機化合物を生成するが,最も特徴のあることは膨大な数の各種有機化合物をつくることである。これは炭素が最も典型的な非金属元素であって,同じ元素の原子どうしが連なって結合する現象,すなわちカートネーションcatenationの現象を示すことによるものである。この傾向は全元素中で炭素が最も強く,一般には周期表中での位置が炭素から遠い元素ほど現れ方が減少する。… ※「catenation」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 |
