Answer» Usually we come across anomalies in the trend's of periodic properties for example the size (Atomic Radius Value from Raymond 9th Edition) Of Gallium {135 pm} as opposed to the basic trend that atomic size increases down the group. This is usually attributed to the fact that the poor shielding of nuclear CHARGE by intervening D orbitals leads to greater hence the radius is less as opposed to the trend. If that's the reason why don't we observe similar effects for other groups: LIKE group 15 having Phosphorus {110 pm} and Arsenic {120 pm}. [Here the Size doesn't increase much but is still significant as COMPARED to changes taking place in group 13] where the size actually increases even when there are D orbitals to intervene. There ANOTHER example of Indium{166 pm} and Titanium {171 pm} both belong to Group 13. As compared to other these Two Members have the Lowest increase in Atomic Radius. ▶ Sorry the kind of Answer that came in my mind I GAVE!!
