Answer

Answer:

Atomic radii decrease slightly and then start to increase.

Brief Explanations:

As transition - metals move left to right, effective nuclear charge increases initially causing atomic radii to decrease. But as electrons start to pair in d - orbitals, electron - electron repulsion increases and atomic radii start to increase.
