Group Number of Technetium (& Uses, Sources ... 2022

As anyone would guess, every atom has a group name assigned, even Technetium. But how do we know what is the group name for an atom of Tc?

First of all, if we know the atom symbol (or name), let's say Tc, we can open any periodic table and search for Technetium. If the periodic table is complete just scroll up and read the number on the top (from 1 to 18).

In the case of Technetium the group number is 7. However there is a lot of funny facts about Technetium that most people don't know. Shall we have a look?
