Ca^(2+) has a smaller ionic radius than ...

`Ca^(2+)` has a smaller ionic radius than `K^(oplus)` because it has `"………" .

Text Solution

Verified by Experts

The correct Answer is:
Higher charge density
`Ca^(2+)` has a smaller ionic radius than `K^(o+)` because it has higher charge density `(("charge")/("size") "ratio")`. In isoelectronic species, as the number of protons (atomic number) goes on increasing, size goes on decreasing due to stronger attraction on the electrons.
