The inert pair effect refers to the tendency of the outermost s-electrons in heavier p-block elements to remain non-bonding, thereby reducing the oxidation state of the element. This effect increases down a group in the periodic table, as the s-electrons become more stable and less reactive due to increased shielding and distance from the nucleus. To enhance the inert pair effect in an atom, one must focus on elements with higher atomic numbers in groups 13 to 16, where the effect is more pronounced.
