The shielding effect is a phenomenon by which the attraction of the nucleus on valence electrons is reduced due to inner electrons repulsions.


Greater is the size of atom greater will be shielding effect.


The shielding effect is actually a screening effect. 
In the periodic table shielding effect increases top to bottom in a group Due to increases in the number of electrons in the inner shells
In the periodic table, this effect decreases from left to right in a period due to no change in the number of shells.
