It actually means this. One of fifteen metallic elements from lanthanum to lutetium.
The 4f series is referred to as the Lanthanides.
Atoms first occupy the 4f level in the Lanthanide series, beginning with Cerium (Ce).
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.
It depends on the periodic table. Some have 14 lanthanides and some have 15 lanthanides. Refer to the related link for a Wikipedia article on the lanthanides for more information.

Wht is the difference between Lanthanides and Actinides?
The 4f series is referred to as the Lanthanides.
describe the complex formation by lanthanides?
Atoms first occupy the 4f level in the Lanthanide series, beginning with Cerium (Ce).
Actinides and lanthanides lose electrons and form cations.
Lanthanides have 6 electron shells. Actinides have 7 electron shells.
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.
