The order of screening effect of electrons of s, p, d and f orbitals of a given shell of an atom on its outer shell electrons is * Thinking process:To solve question, keep in mind that shielding effect represent the repulsive force felt by the valence shell from the electrons presents in the inner shells.

Assertion : Atomic radius of gallium is higher than that of aluminium Reason : The presence of additional d-electron offer poor screening effect for the outer electrons from increased nuclear charge.
