The 4f series is referred to as the Lanthanides.
Lanthanides.
Lanthanides are in the '4 f ' block (of the so-called 'secundairy transitionals', atom number 58 to 71) filling up 4f orbital (1 to 14 electrons)
4F
Atoms first occupy the 4f level in the Lanthanide series, beginning with Cerium (Ce).
3d-block elements or tranformation elements and 4f-block elements or lanthanides and actinides
The 4f subshell is being filled for the rare earth series of elements.

The elements in the horizontal rows are called periods.

These are the lanthanides or the 4f block; they should include lanthanum were it not for a contraction that lags lanthanum in the d block.
Lanthanide: The first series of inner transitionelements which goes from cerium to lutetium.
The elements in the 8 main columns of the Pperiodic Table are called Groups. Groups 1 and 2 are separated from Groups 3 to 8 by a block of elements called the Transition Series and the columns in this series have no specific names.
