The lanthanide (/ ˈ l æ n θ ə n aɪ d /) or lanthanoid (/ ˈ l æ n θ ə n ɔɪ d /) series of chemical elements [a] comprises at least the 14 metallic chemical elements with atomic numbers 57–70, from lanthanum through ytterbium. In the periodic table, they fill the 4f orbitals.
30 cze 2023 · The Lanthanides consist of the elements in the f-block of period six in the periodic table. While these metals can be considered transition metals, they have properties that set them apart from the rest of the elements.
1 sty 2013 · Lanthanide elements (Ln: La-Lu; 57-71) belong to the rare-earth series of elements (Sc, Y, and Ln). They present specific chemical, optical, and magnetic properties that are a consequence...
understand that lanthanides differ in their properties from the s- and d-block metals; recall characteristic properties of these elements; appreciate reasons for their positioning in the Periodic Table; understand how the size of the lanthanide ions affects certain properties and how this can be used in the extraction and separation of the ...
22 sie 2019 · Rare earth (RE) elements—the lanthanides, yttrium, and scandium—are critical components of numerous modern technologies, from permanent magnets in wind turbines and electric car batteries, to lasers and phosphors, to medical imaging agents.
