Group Number of Chlorine (& Uses, Sources ... rev. 2022

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

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

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