Question

Ionic radii are
(a) inversely proportional to effective nuclear
charge
(b) inversely proportional to square of effective
nuclear charge
(c) directly proportional to effective nuclear
charge
(d) directly proportional to square of effective
nuclear charge

Answer 1

ANSWER

inversely proportional to effective nuclear charge

SOLUTION

The radius of the ion depends on the effective nuclear charge, more the charge, more heavily the electrons are attracted towards the center and lesser in the size. Hence the ionic radii are inversely proportional to effective nuclear charge

Answer 2

Ionic radii are

(a) inversely proportional to effective nuclear charge✔✔

(b) inversely proportional to square of effective

nuclear charge

(c) directly proportional to effective nuclear

charge

(d) directly proportional to square of effective

nuclear charge
