8. Actinides: ( ak'tin-īdz ), Those elements with atomic numbers 89 to 103, below the lanthanides in the Periodic Table
9. The first element of the actinides, actinium gave the group its name, much as lanthanum had done for the lanthanides.
10. The active optical waveguide is doped with ions of transition metals or metals from the groups of Lanthanides or Actinides.
11. However, Actinides show a greater range of oxidation states than lanthanides, as 5f, 6d and 7s are of comparable energy
12. As with most lanthanides and actinides, actinium exists in the oxidation state +3, and the Ac3+ ions are colorless in solutions.
13. Actinium has similar chemical properties to lanthanum and other lanthanides, and therefore these elements are difficult to separate when extracting from uranium ores.
14. This color behavior is similar to what Mosander and the other early workers in the lanthanides would have seen in their extracts from the gadolinite minerals of Ytterby.
15. Actinide (plural Actinides) (inorganic chemistry) Any of the 14 radioactive elements of the periodic table that are positioned under the lanthanides, to which they have similar chemistry
16. At 4.96 eV, it is the lowest of all Actinides and lanthanides because of strong relativistic shielding that makes it easier to pluck off lawrencium’s weakly bound 7p electron.
17. Illustrative of its chelating abilities, citric acid was the first successful eluant used for total ion-exchange separation of the lanthanides, during the Manhattan Project in the 1940s.
18. The 2 rows that have been separated out of the main table are rare-earth elements, or lanthanons (lanthanides) in the first period and Actinons (actinides) in the next period.
19. The components are preferably Cr, Mo, Re and/or W, Al, Ti, Ta, Hf, Si, reactive elements comprising actinides and lanthanides, C, optionally the components Zr and/or B.
20. Increasing K2O/Na2O ratios are accompanied by an increase of the absolute lanthanide concentrations and by a progressive accumulation of the lighter lanthanides in the sequence: doleritic olivine basalt, pigeonite tholeyite, tholeyite from the Schaumberg sill, plagiaplite.
21. As nouns the difference between actinide and Actinoid is that actinide is (inorganic chemistry) any of the 14 radioactive elements of the periodic table that are positioned under the lanthanides to which they have similar chemistry while Actinoid is (inorganic chemistry) actinide
22. The Lanthanides and Actinides: Synthesis, Reactivity, Properties and Applications constitutes an introduction to and comprehensive coverage of f-block chemistry encompassing the following areas: periodicity, natural occurrence and extraction, separations, electronic structure, coordination chemistry, organometallic chemistry, small molecule activation, catalysis, organic synthesis applications
23. The Actinides (sometimes called actinoids) occupy the "bottom line" of the periodic table — a row of elements normally separated from the others, placed at the foot of the chart along with the lanthanides. Both of these families exhibit unusual atomic characteristics, properties that set them apart from the normal sequence on the periodic table.
