Group Number Actinium (Ac) (& Color, Uses ... 2022

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

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

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