Question

Al and Ga have the same covalent radius because of
  1. Greater shielding of s - electrons of Ga atoms
  2. Poor shielding of s- electrons of Ga atoms
  3. Greater shielding of d - electrons of Ga atoms
  4. Poor shielding of d - electrons of Ga atoms

A
Poor shielding of s- electrons of Ga atoms
B
Greater shielding of d - electrons of Ga atoms
C
Greater shielding of s - electrons of Ga atoms
D
Poor shielding of d - electrons of Ga atoms
Solution
Verified by Toppr

Poor shielding increases the effective nuclear charge, thereby decreasing atomic radius. This effect counterbalances the effect of increase in atomic radius due to addition of another shell.
