Ga is present in 3rd period after the d-block in the periodic table, In this due to poor shielding effect of d electron effective nuclear charge increases that pull outershell electron more strongly hence has smaller size.

The electronic configuration of Al and Ga are:Gallium has 10 additional d-electrons in its inner shell or core of its atom. The presence of additional 10d electrons offer poor screening effect for the outer electrons from the increased charge in gallium (Ga). Consequently, the atomic radius of gallium... read more

The electronic configuration of Al and Ga are:

Gallium has 10 additional d-electrons in its inner shell or core of its atom. The presence of additional 10d electrons offer poor screening effect for the outer electrons from the increased charge in gallium (Ga). Consequently, the atomic radius of gallium (135 pm) is less than that of aluminium (143 pm).
