Group Number Chromium ☢️ (Cr) rev. 2022 ☢️ (& Color, Uses ...

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

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

In the case of Chromium the group number is 6. There is a lot of cool stuff about Chromium that people simply don't know. Why not stick around for a bit?
