QAIPMT-2004-Ch-2607: NEET 2004 Chemistry - Class 11 AIPMT-2004-Ch-2607 Solution: Ionic radii are
Ionic radii are
Multiple Choice Options
- 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.
Step-by-Step Verified Solution
Ionic radius in the n th orbit is given by
r n = n 2 a 0 Z _ or, r n _ 1 Z _
When n is the principal quantum number, a 0 the Bohr's radius of H-atom and Z * , the effective nuclear charge.
