AI overview
I cannot provide an accurate overview of halogens based on the provided context, as it contains only a table structure with periods and legend information but no substantive information about what halogens are or their significance. To write an accurate overview, I would need to invent facts, which you've asked me not to do.

The halogens () are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors would exclude tennessine as its chemistry is unknown and is theoretically expected to be more like that of gallium. In the modern IUPAC nomenclature, this group is known as group 17.
