Ionic radii vary in: - Vidyadip

MCQ

Ionic radii vary in:

A
Inverse proportion to the effective nuclear charge.
B
Inverse proportion to the square of effective nuclear charge.
C
Direct proportion to the screening effect.
D
Direct proportion to the square of screening effect.

✓

Answer

Inverse proportion to the effective nuclear charge.

Direct proportion to the screening effect.

Explanation:

$\text{Ionic radius}\propto\frac{1}{\text{eddective unclear charge}}$

Further, ionic radius increases as the screening effect increases

$\text{Ionic radius}\propto\text{screening effect}$
