Halogen: Characters, History & Applications

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…
