Question:medium

Chloride ion and potassium ion are isoelectronic. Then

Show Hint

For isoelectronic species: Radius \(\propto \frac{1}{\text{Atomic Number (Z)}}\). The species with the highest number of protons will always be the smallest.

Their sizes are same
Cl\(^{-}\) ion is bigger than K\(^+\) ion
K\(^+\) ion is relatively bigger
Their sizes depend on other cation and anion

Show Solution

The Correct Option is B
