11. Both elements are lanthanides and have very similar physical and chemical properties. 12. Cyclooctatetraene forms organometallic complexes with some metals, including yttrium and lanthanides . 13. Lanthanide triflates can dramatically cut the impact of these syntheses.14. DOTA is used as a complexing agent, especially for lanthanide ions. 15. As a result of this nearly all lanthanide silylamides are commercially available. 16. Across the lanthanide series, electrons are added to the 4f shell. 17. Traditional virus diagnostic procedures are being replaced by sensitive immunoassays with lanthanides . 18. Gadolinium ( III ), like most lanthanide ions, forms dentate ligand. 19. The lanthanides elute in order of decreasing atomic number. 20. The lithophile elements include : W and the lanthanides .
