Answer:
Br has large atomic radius. The atomic size decreases from left to right in a period due to the increase in the nuclear charge which pulls the electrons closer to the nucleus. So Cl has less radius

Bromine is larger atom
Explanation:
As we move from up to down a group of elements in the period table, the size of the atom increases down the group as the number of electrons increase. So the distance between the electrons in the outer shell and the nucleus increases, thus decreasing the nucleic attraction on those electrons. Chlorine is above Bromine in Group 17. So Bromine has a bigger atom with one more electron shell than Chlorine.
