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.

Apr 4, 2025 · Lanthanide, any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57–71). With scandium and yttrium, they make up the rare-earth metals.

Feb 4, 2021 · Chemists refer to these 15 elements using the symbol Ln. They are called “lanthanides” because they share properties in common with lanthanum. Here is a list of the lanthanides, a look at their common properties, their uses, and other facts.

Jun 30, 2023 · What causes the Lanthanide Contraction? Why do Lanthanides exhibit strong electromagnetic and light properties? What do the Lanthanides have in common with the Noble Gases?

May 3, 2019 · Learn about the characteristics of elements 57-71 known as the lanthanide elements. Lanthanides are one of the rare earth groups.

Lanthanides are metals that are related to each other in how they behave. Most of them slowly turn into their hydroxides when they are placed into water, like the alkali metals. They usually form a coating of oxide when placed in the air, like most metals. Lanthanides, with Scandium and Yttrium, are called rare earth elements.

Lanthanides refer to the collective designation of 15 elements from No. 57 to No. 71 elements with similar chemical properties in the periodic table of elements.

Apr 28, 2024 · Although lanthanoids, scandium, Sc, and yttrium, Y, are sometimes called rare earth elements, they are relatively abundant in the earth’s crust. With the exception of promethium, Pm, which does form a stable isotope, even the least abundant thulium, Tm, and lutetium, Lu, are as abundant as iodine.

Lanthanide Series - Elements with atomic numbers from 58 to 71 are called Lanthanides. Understand the concepts of Lanthanide Contraction, Physical, Chemical properties, uses and more.
