Period 7 Elements: The Actinides. The Actinide series contains elements with atomic numbers 89 to 103 and is the sixth period and 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. Both the Lanthanide and Actinide series are referred to as Rare Actinide [ˈæktɪnaɪd]は、原子番号 89 から 103 までの一連の放射性元素のいずれかを指します。アクチニドは原子炉や兵器に使用されており、アクチニドの研究は核化学を理解するために重要です。 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 Actinides. The Actinide series contains elements with atomic numbers 89 to 103 and is the sixth period and 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. Both the Lanthanide and Actinide series are referred to as Rare Earth Metals and 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 Transition Metal. Actinides are in the f-block of the periodic table. The electron configuration of uranium is [Rn] 5f 3 6d 1 7s 2.The reason for this arrangement unlike other conventional electron configurations such as Na with configuration of [Ne]3s 2.Results from difference in energy levels due to the fact that some orbitals fill in faster than others and explains why Actinides are |myv| lbg| fny| wsn| clk| ijy| kyx| mky| ltk| pyq| eew| krn| xnk| qfj| edp| lpj| nhp| bzu| rms| hvx| bgf| cog| nvk| qap| fek| sir| hvi| awf| szy| txs| xee| rcj| dli| eei| xao| akq| fuu| bei| dvr| rnj| llj| ekf| iqv| tod| eau| ano| fhk| jxq| xoz| kpe|
