An illustration of the shape of the 4f orbitals.

The lanthanide series is defined by the progressive filling of the 4f orbitals. These seven orbitals have the following ml values:

ml=0, ±1, ±2, ±3

ml=0 are real, all the others are complex and so linear combinations must be taken to obtain real orbitals.








General set

These are produced by simply taking linear combinations of ml=±1, ±2, ±3
