Ionic radii are

A

inversely proportional to the effective nuclear charge

B

inversely proportional to the square of effective nuclear

C

directly proportional to the effective nuclear charge

D

directly proportional to the square of effective nuclear charge

Text Solution

Verified by Experts

The correct Answer is:
A
According to Bohr' theory,
`r_(n) = (n^(2)r_(1))/(Z)`
Thus, the ionic radii are inversely proportional to the effective nuclear charge `(Z_(eff))`.
