Explanation / Answer

Across the row the newly added electron is entered into same shell. Where as in groups the newly added electron is entered into new shell.

Across the row of transition elements the numberof electrons in the outermost principal energy level is significantly different. as another proton is added to nucleus with each successive element. Another electron added but electron goes into an roughly the same orbital.so even though the atomic number of Cu is higher than that of V the outermost electron experiences higher effective nuclear charge. Thus the radii of two elements are nearly the same.
