- 8: Lanthanide and Actinide
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.
27 Ιουν 2019 · The lanthanides and actinides are separated from the rest of the periodic table. Explore why these elements are below the main body of the table.
1 Δεκ 2022 · The lanthanides and the actinides make up the f block of the Periodic Table. The lanthanides are the elements produced as the 4 f sublevel is filled with electrons and the actinides are formed while filling the 5 f sublevel.
13 Ιαν 2023 · The Actinide series contains elements with atomic numbers 89 to 103 and is the third group in the periodic table. The series is the row below the Lanthanide series, which is located underneath the main body of the periodic table.
30 Ιουν 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.
4 Φεβ 2021 · The lanthanides are located on the top row of the two rows of elements found below the main body of the periodic table. Placing the lanthanides and the actinides (the row below the lanthanides) below the other elements is just a matter of aesthetics.
