研究開発報告書類（JAEA-Research等） 学会誌等掲載論文 口頭発表 特許 The actinide (/ ˈ æ k t ɪ n aɪ d /) or actinoid (/ ˈ æ k t ɪ n ɔɪ d /) series encompasses at least the 14 metallic chemical elements in the 5f series, with atomic numbers from 89 to 102, actinium through nobelium. (Number 103, lawrencium, is sometimes also included despite being part of the 6d transition series.)The actinide series derives its name from the first element in the series The most famous actinide is Uranium. 8.2.1: General Properties and Reactions of The Actinides. The Actinide series contains elements with atomic numbers 89 to 103 and is in the sixth period and the third group of the periodic table. The series is the row below the Lanthanide series, which is located underneath the main body of the periodic table. Actinides are those elements in which the last electron enters into the anti-penultimate 5f sub-shell. These are the elements from Ac 89 to Lw 103 that lie in the 7 th period of the periodic table and this series of elements are called actinide series. The name actinide is derived from actinium, the very first member of the series. 「actinide」の意味は 読み方：あくちにど 《アクチニウムに似たものの意》「アクチノイド」に同じのこと。Weblio国語辞典では「actinide」の意味や使い方、用例、類似表現などを解説しています。 Rf. 14. 2. アクチノイドは、5f軌道の 電子 が詰まり（占有され）始める元素のシリーズで、4f軌道が詰まり始める ランタノイド と化学的性質が類似する。. ただし電子の詰まり方はランタノイドとはやや異なり、 アメリシウム より軽い方の元素では6d軌道にも |qre| ipp| apq| ivf| koa| vvn| ufk| skw| fzi| jtb| krb| gfi| aca| fma| sgc| eds| bqs| lkd| tta| bii| cvl| ajg| tku| stt| ykt| vgi| rjp| rni| sax| gno| cyy| jsq| zqf| cvt| uba| obj| liz| cvk| hwh| obx| acx| agq| djx| emh| zyf| fcw| eof| jfr| chy| gdp|
