Group Number Thulium (Tm) (& Color, Uses ... 2022

All atoms have a group name assigned, even Thulium. Ok but how do we know what is the group name for an atom of Tm?

If we know the symbol, let's say Tm, we may then open any periodic table and search for Thulium. Any decent periodic table should have the group numbers when you scroll up starting from the element you found.

In the case of Thulium the group number is lanthanides. There is a lot of cool stuff about Thulium that people simply don't know. Why not stick around for a bit?
