...This is because the electron configuration of the atom is s 2 p 6 (only helium has s 2 ) in the outermost shell, which creates a closed shell and a safe configuration, and also because the ionization potential is high, which makes it chemically inactive. For this reason, it is also called inert gas or noble gas. It was thought that none of the elements could form true compounds, but XePtF 6 was first created by N. Bartlett of Canada in 1962 for xenon, which has the lowest ionization potential, and since then compounds of Xe and Kr have been created to this day. ... *Some of the terminology explanations that mention "noble gas" are listed below.

…これは,原子の電子配置が,最外殻でs2p6(ヘリウムのみはs2)となり,閉殻をつくり安全な配置をとるためであり,またイオン化ポテンシャルが高く,化学的に不活性な原因となっている。このため,不活性気体(不活性ガス)inert gasあるいは貴ガスnoble gasということもある。いずれの元素も真の意味での化合物をつくることはないと考えられていたが,イオン化ポテンシャルの最も低いキセノンについて1962年カナダのバートレットN.BartlettによってはじめてXePtF6がつくられ,それ以来今日までにXeおよびKrの化合物がつくられている。… ※「noble gas」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 |
