inert pair effect is actually the reluctance of the ns electrons to take part in reaction. I am trying to explain it in terms of energy. This phenomenon is found in p-block elements. We know that the shielding effect of d- and f-orbitals is least effective . as a result of this the the effective attraction of the nucleus on the outer s-orbitals increase and this makes t difficult for them to be removed. Now ,in case of higher members of the group due to their large atomic radii, the bond enthalpy is less. this bond energy is not sufficient enuf to remove the outer s electrons which are now held more tightly due to the intervening d- and f-orbitals. This is the cause of inert pair effect. Due to this the higher members tend to show OS 2 less than the gr. OS. RATE ME IF SATISFIED.

Inert pair effect is simply the reluctance of ns orbital electron pair to take part in bonding.

Eg, In case of p-block elements, the valancy of +3 becomes more pre-dominant than +5 as the ns electrons do not participate in bonding.

Hope you find this useful!

All the best!

Heavy elements in certain groups of the periodic table form compounds in which they exist with oxidation states two less than the common oxidation state for that group.

 For example, although the common oxidation state for elements in group 4 is +4, most elements in the group can also exist in oxidation state +2.

This is because of the inert pair effect. In large atoms, such as those of tin and lead, some outer-shell electrons are not as well shielded as those in the inner core.

They are therefore sucked into the inner core of electrons and thus become inert.
