> F-block
The
f-block
of the
periodic table of elements
consists of those elements for which, in the atomic
ground state
, the highest-energy
electron
s occupy f-
orbital
s. Unlike the other blocks, the conventional divisions of the f-block follow
period
s of similar
atomic number
rather than
group
s of similar electron configuration. Thus, the f-block is divided into the
lanthanide series
and the
actinide series
.
