The following represents the electronic configuration and its associated term symbol for the ground state neutral gaseous atom. The configuration associated with neodymium in its compounds is not necessarily the same.
Ground state electron configuration: [Xe].4f4.6s2
Shell structure: 184.108.40.206.8.2
The image below is a schematic representation of the shell structure of neodymium - not what the atom of neodymium "looks like".
