Bohr proposed that an electron is found only in specific circular paths, or orbits, around the nucleus.
If you think to the electron configuration of lutetium this is: [Xe]4f14.5d1.6s2.

are you looking for the most recent electron orbit model or a history? There have been a few over time.
Electrons enter the orbitals on the basis of increasing energy of sub-shells. Also, when an electron occupies an orbital another electron cannot occupy that orbital until all other orbitals of that sub-shell have atleast 1 electron.
