Group Number Erbium (Er) (& Color, Uses ... 2022

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

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

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