Atomic radius is defined as the distance between the nuclei of 2 identical atoms that are bonded together

Now, from periodic tables, chromium has a calculated atomic radius of 1.66 Å while iron has a calculated atomic radius of 1.56 Å

Thus, chromium has a bigger atomic radius than iron.

So the statement is false.
