Group Number Cobalt (Co) (& Color, Uses ... 2022

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

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

In the case of Cobalt the group number is 9. There is a lot of cool stuff about Cobalt that people simply don't know. Why not stick around for a bit?
