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

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

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

In the case of Iodine the group number is 17. However there is a lot of funny facts about Iodine that most people don't know. Shall we have a look?
