Question

The inert pair effect is the tendency to form ions two units lower in charge than expected from the group number of heavier $p$ - block elements.

If the statement is true enter 1 else enter 0.

Answer 1

The inert pair effect is the tendency to form ions two units lower in charge than expected from the group number of heavier p-block elements.

For example in group IVA, the +2 oxidation state of Pb is more stable than +4 oxidation state as 6s electrons do not participate in the ionization process and remain as inert pair.
