Answer / muhammad ehsan ullah
F subshell has less shielding effect, so, it is more strongly attracted by nucleas, and it penetrates behind s subshell of (n-2) orbital. Due to the presence of f subshell at penultimate position, f block elements are called inner transition elements.
While,
d subshell is present at valance/ outermost position in d block elements, so, they are also called outer transition elements.

Answer / monojit mitra
Due to the less screening effect of the f-orbitals they are
attracted mostly by the nucleus rather than the d-orbitals.
As a result of this the f-block elements are called inner
transition elements while d-block elements are called outer
transition elements.
