Question

Difference between inert pair effect and shielding effect

Answer 1

Answer:

Inert Pair effect arises due to the tendency of outer s orbital to not take part in the bonding. Hence there is increase in stability of oxidation state lower down the group that is 2 less than the group oxidation state.

Shielding effect :If the electron is in s orbital, it means it is nearest to nucleus and if in f shell, it means it is farthest from nucleus. Since, atomic shielding depends on electron density in a orbital and electron density is very less for d and f orbitals, hence it has poor shielding effect as compared to s and p orbitals.
