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

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

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

In the case of Tantalum the group number is 5. However there is a lot of funny facts about Tantalum that most people don't know. Shall we have a look?
