Ionic radii are

A

Directly proportional to effective nuclear charge

B

Directly proportional to square of effective nuclear charge

C

Inversely proportional to effective nuclear charge

D

Inversely proportional to square of effective nuclear charge

Text Solution

Verified by Experts

The correct Answer is:
C
Ionic radius in the `n^(th)` orbit is given by `r_(n)=(n^(2)a)/(z) or r_(n)prop(1)/(Z)` where n is principal quantum no., `r_(n)` is bohr's radius of hydrogen atom and Z is the effective nuclear energy.
