Aktinoidy jsou podle současné mezinárodní chemické nomenklatury skupinou patnácti chemických prvků počínajících aktiniem, tedy prvků s protonovým číslem 89 až 103 (dříve se pod tento název řadilo pouze čtrnáct prvků následujících za aktiniem). V zemské kůře se vyskytují ve využitelných množstvích thorium (8,1 ppm) a uran (2,3 ppm). Druhý jmenovaný je v…
The analysis highlights Overview, Chemické a fyzikální vlastnosti and Využití as prominent areas in the source structure around Aktinoidy.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
