The second and third rows of transition elements

Question:

 The second and third rows of transition elements resemble each other much more than they resemble the first row. Explain why?

Solution:

Due to poor f orbital shielding, effective nuclear charge increases and there is a contraction in the size of the third-row elements. This contraction in size is called

Lanthanide contraction. The second and third row of transition elements have similar atomic radii and therefore they resemble each other more.
