How does the electropositivity vary down the group of halogens? 

Text Solution

Verified by Experts

All halogens are non-metals. Electro-positivity increases down the group. Fluorine does not exhibit positive oxidation states. Chlorine, bromine and iodine exhibit positive oxidation states.
However, only iodine is known to form cation, It with reasonable stability.
