What do you call the atomic series from 51-71?

The atomic series from atomic numbers 51 to 71 corresponds to the group of elements known as the "lanthanides" and the "post-transition metals." Specifically, it includes elements such as antimony (Sb, atomic number 51) and ends with lutetium (Lu, atomic number 71). The series includes elements like tellurium, iodine, xenon, cesium, and others, but primarily features the lanthanide series starting from cerium (Ce) to lutetium (Lu).


What family does cerium belong to?
