Question

Define inert pair effect​

Answer 1

Answer:

The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals.

As a result, the inert pair of ns electrons remains more tightly held by the nucleus and hence participates less in bond formation.

Answer 2

Answer:

The Inert Pair Effect is often considered to be a minor effect on the properties of an element. But this effect is of profound importance not only on the element but also on the trends of the periodic table.

 The inert-pair effect occurs mainly in elements that come after the transition elements in the periodic table. It is the tendency of the outermost s-orbital electrons to not participate in chemical reactions.
