Question

What is meant by screening effect and Inert pair effect

Answer 1

Answer:

screening effect: The shieldingeffect describes the balance between the pull of electrons on valency electrons and the repulsion forces from inner electrons.

The inter pair effect explains by common ions of Pb power Pb 4 + and power Pb 2 +and not just Pb power 4 + as we might expect from the octet rule.

Answer 2

Answer:

Screening effect

Screening effect is also known as the shielding effect. The phenomenon which occurs when the nucleus reduces its force of attraction on the valence electrons due to the presence of electrons in the inner-shell.

Inert pair effect

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.
