The atomic radius of Br is smaller than the ionic radius of Br-
Explanation:
The atomic radius of Br is the smallest of the atoms in the fourth period besides Kypton. The radius of the electron density shell remains the same but the number of protons creating a pull increases.
The ionic radius of Br- is larger than the atomic radius of Br because there is one more electron but no more protons.
For additional help: Atomic radius starts at 6:00 and and ionic radius at 7:12.
