A. Br > I > Cl > F

B. F > I > Cl > Br

C. F >Cl > Br >I

D. I > Br > Cl >F

E. Cl > Br >F >I

CORRECT ANSWER IS C

EXPLANATION: The halogen are found in group seven of the periodic table. They are often referred to as salt formers. They are known for their strong reducing power. The halogen of group seven start with the yellow gaseous Fluorine, followed by greenish yellow gaseous Chlorine, followed by reddish brown liquid Bromine, followed by black solid Iodine. The decreasing order is F >Cl > Br >I. There is also the radioactive astatine which is not part of the question. The etymology of the name halogen shows that it is a Greek word, where halo means salt and gen means produces. In other word, they are salt formers as the can combine with metals to form salt.
