Which of the following statements about atomic radii accurately describes the data below?
  • a)
    The elements right after the d-block experience an expansion due to the repulsion created by the d electrons such that period 4 non metals are substantially larger than period 3 nonmetals.
  • b)
    The minima of the graph correspond to the halides because they have the greatest effective nuclear charge.
  • c)
    The transition metals have relatively the same atomic size moving across the group because their valence shell, which is the s orbital, essentially remains the same.
  • d)
    The peaks of the graph correspond to the noble gas configurations because they have fully-filled orbitals.
Correct answer is option 'C'. Can you explain this answer?

Solution:
  • The atomic size of transition metals remains relatively consistent across a period.
  • This consistency is because the valence shell primarily involves the s orbital, which does not change much.
  • As a result, the atomic radii of transition metals do not significantly increase or decrease across the group.
