Question
Which of the following accurately represents the increasing order of atomic radii in Group 13 elements?
Answer: B
💡 Solution & Explanation
Due to 'transition contraction' caused by the poor shielding of the ten 3d electrons, the effective nuclear charge on Gallium increases, making its atomic radius smaller than that of Aluminium.
