Which of the following is correct?

A
Ionic radius is proportional to atomic number.
B
Ionic radius is inversely proportional to atomic mass.
Correct answer
C
Ionic radius is inversely proportional to effective nuclear charge.
D
All are correct.

Solution

(3) is correct answer because $r_{\text {ionic }} \propto \frac{1}{Z_{e f f}}$

Hence, the correct answer is option: 'C'.
