Group Number Helium (He) (& Color, Uses ... 2022

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

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

In the case of Helium the group number is 18. There is a lot of cool stuff about Helium that people simply don't know. Why not stick around for a bit?
