Question

The increasing order of atomic radii of the following Group 13 elements is (A) Al < Ga < In < Tl (B) Ga < Al < In < Tl (C) Al < In < Ga < Tl (D) Al < Ga < Tl < In

As on moving down the group atomic size increase so Ga < Al < ln < TI. Here size of Ga is less than that of Al due to poor screening effect in Ga.

Q. The increasing order of atomic radii of the following Group $13$ elements is

Al < Ga < In < Tl

Ga < Al < In < Tl

Al < In < Ga < Tl

Al < Ga < Tl < In

As on moving down the group atomic size increase so Ga $< A l < ln <$ TI. Here size of Ga is less than that of Al due to poor screening effect in Ga.
