4f is a valid orbital.
three nodes
There are 36 types of orbitals in the sixth shell.
I would think the s orbital, because it is closer to the nucleus, and because the outer energy level holds more energy than the inner ones.
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)
there are 16 orbitals in a n=4 shell *since there are 2 electrons in each orbital, that makes 32 electrons total here
4f orbital

4f
The element cerium has a single electron in the 4f orbital. Its electron configuration is [Xe] 4f1 5d1 6s2.
in 5s it is filled but in 4d or 4s its half
4f subshell has the highest energy. A f subshell has the highest energy among all the subshells in any shell.

The specific orbital within a sublevel- apex
They are further away from the nucleus and easier to remove (requires less energy), i.e. first ionization is less.
