The five elements; Fluorine (F), Chlorine (Cl), Bromine(Br), Iodine (I) and Astatine (At) belonging to VII A Group of the modern periodic table are collectively referred as halogens. The last element Astatine is radioactive and is very short lived hence generally excluded from the study. The word halogen is derived from the Greek words Halos […]
