If the valence electrons are being added to the 4f orbitals, that means the element is lanthanides or actinides which further proves that the element is a heavy element and a member of f -block.
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)
some atoms have 5, some have none. the max is 5
there are 16 orbitals in a n=4 shell *since there are 2 electrons in each orbital, that makes 32 electrons total here
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
for the case of n=4 the available orbitals include 1s 3p and 5d, a total of 9 electron orbitals which can occupy 18 electrons. There are 18 elements in the 4th row which coincides with the 9 available orbitals.
The maximum number of electrons that can exist in 4f orbitals is 14.-pg. 110 Modern Chemistry table 2:)
Maximum capacity of electrons in f-orbitals is 14, so 4f orbitals may have 1 to 14 electrons.

the correct order is-4s>4p>4d>4f this is because of the shape of the orbitals
The lanthanides, the inner transition metals from 57La through 71Lu.
There are 36 types of orbitals in the sixth shell.
The subshells of 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 4f act like core orbitals. This understanding of the configuration of the atom helps us to understand why electrons and atoms behave the way they do.
2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10
