Explanation:

Elements in the same group (vertical column) of the periodic table have similar chemical properties because they have the same number of valence electrons. Chlorine (Cl) is in Group 17 (halogens). Bromine (Br) is also in Group 17, located below chlorine. Sulfur is in Group 16, oxygen in Group 16, and argon in Group 18 (noble gases), so they don't have similar properties to chlorine as bromine does.

Answer:

bromine below it
