what is inert pair effect

when and where to apply it?

6 years ago


Answers : (1)


Dear Tarun,

Inert pair effect is the tendency of the outermost s electrons to remain nonionized or unshared in compounds of post-transition metals. The term inert pair effect is often used in relation to the increasing stability of oxidation states that are 2 less than the group valency for the heavier elements of groups 13, 14, 15 and 16.The situation in groups 14, 15 and 16 is that the stability trend is similar going down the group, but for the heaviest members, e.g. lead, bismuth and polonium both oxidation states are known.the valence electrons in an s orbital are more tightly bound are of higher energy than electrons in p orbitals and therefore less likely to be involved in bonding.

The set representing the correct order of first ionisation potential is- K Be>Mg>Ca B>C>N Ge>Si>C
In the period the ionisation potential increases and in the group it decreases. thus, Be Mg and Ca are in group therefore othe order is correct.
