They are called lanthanides (as well as scandium and yttrium).
The lanthanides are a series of elements that are placed at the bottom of the periodic table. They are located in the f-block, specifically in the period below the main body of the periodic table. The lanthanides have atomic numbers 57-71.
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
The elements of the 4f series are called lanthanides. They are a group of metallic elements that have similar properties and occupy the f-block of the periodic table.
Cerium belongs to the lanthanide series of chemical elements, which are part of the f-block in the periodic table.

They are called lanthanides (as well as scandium and yttrium).
Rare earth is another name (old) for lanthanides or lanthanoids.
The lanthanides are a series of elements that are placed at the bottom of the periodic table. They are located in the f-block, specifically in the period below the main body of the periodic table. The lanthanides have atomic numbers 57-71.
The lanthanides get their name from the element lanthanum, which was the first in the series to be discovered. The actinides get their name from actinium, which was the first element in this series to be discovered.
Wht is the difference between Lanthanides and Actinides?
describe the complex formation by lanthanides?
Scandium and Yttrium (actually many of the lanthanides and actinides are rare as well)
Some lanthanides are radioactive, such as promethium. However, most lanthanides found in nature are stable.
Actinides and lanthanides lose electrons and form cations.
