The ionic size of Cl^(-) is greater than...

The ionic size of `Cl^(-)` is greater than that of `K^(+)` ion, though they are isoelectronic.
Explain.

Text Solution

Verified by Experts

Nuclear forces of attraction on valence electrons are higher in `K^(+)` ion than in `Cl^(-)` This in due to
the greater nuclear charge of `K^(+)` ion. So, the ionic size of `Cl^(-)` ino is greater than that of `K^(+)` ion.
