comparing reactivity of different nonmetals\nrank the nonmetals in each set from most reactive (1) to least reactive (3).\nbromine:\nchlorine:\niodine:

Answer

Explanation:

Step1: Recall periodic - table trends

In the halogen group of non - metals (Group 17), reactivity decreases down the group.

Step2: Identify positions in the group

Chlorine is above bromine, and bromine is above iodine in Group 17.

Answer:

Bromine: 2 Chlorine: 1 Iodine: 3
