Group Number of Thulium (& Uses, Sources ... 2022

As anyone would guess, every atom has a group name assigned, even Thulium. But how do we know what is the group name for an atom of Tm?

First of all, if we know the atom symbol (or name), let's say Tm, we can open any periodic table and search for Thulium. If the periodic table is complete just scroll up and read the number on the top (from 1 to 18).

In the case of Thulium the group number is lanthanides. However there is a lot of funny facts about Thulium that most people don't know. Shall we have a look?
