What elements has the smallest atomic radius bromine sulfur chlorine or selenium?

Among bromine, sulfur, chlorine, and selenium, chlorine has the smallest atomic radius. This is because atomic radius decreases as you move from left to right across a period on the periodic table. Chlorine is located on the right side of the periodic table in the 17th group, which indicates smaller atomic radius.
