Cations with electronic configurations of ns2 np6 nd10 exhibit greater polarisation power on anions compared to those with configurations of ns2 np6. This increased polarisation is attributed to their smaller size and poorer shielding effect on outer electrons, resulting in a stronger effective nuclear attraction. In contrast, cations with the ns2 np6 configuration experience a greater shielding effect, leading to reduced nuclear attraction and lower polarisation power.
PREREQUISITESChemistry students, researchers in inorganic chemistry, and professionals studying ionic interactions and bonding characteristics.
This due to the cations which have elctronic configuration ns2 np6 nd10 has a poor shileding effect on outer electrons hence effective nuclear attraction increase. The cations which have configuration ns2 np6 have a greater shielding effect so they have less nuclear attractionShafia Zahin said:Why the cations having electronic structure of ns2 np6 nd10 have more polarisation power on anions than the cations having electronic structure of ns2 np6?
