Does bromine behave the most like krypton in chemical reactions?

I do not think that Bromine behaves like Krypton in chemical reactions. Krypton is very unreactive due to the fact that it has a full stable set of valence electrons, and Bromine is extremly reactive and has high electronegativity because is does not have a full stable set of valence electrons. Although, I do suppose that if a Bromine atom were to become a negative ion (Br+1) by gaining another electron, it would act as if it were a Krypton atom.
