Ionic radii propto (1/Zeff) Zeff→ Effective nuclear charge This Zeff is calculated as follows Zeff=Z- screening constant (σ ) This value of screening constant is based upon the number of electrons in valence shell as well as in penultimate shells.

Q. Ionic radii are

inversely proportional to effective nuclear charge

inversely proportional to square of effective nuclear charge

directly proportional to effective nuclear charge

directly proportional to square of effective nuclear charge

Ionic radii $\propto \frac{1}{Z _{e ff}}$
$Z_{e ff} \to$ Effective nuclear charge
This $Z_{e ff}$ is calculated as follows
$Z_{e ff} = Z -$ screening constant $(σ)$
This value of screening constant is based upon the number of electrons in valence shell as well as in penultimate shells.
