Question
Mention the variation of atomic radii among the group 13 elements. Explain why ?
Open in App
Solution
The correct order of atomic radii in group 13 elements is
B < Al < Ga < In =Tl
The atomic radii increase down the group but the increase is very less at the bottom of the series.
This is because of the screening effect.
