The ionic radii (in \(\mathop A\limits^o \)) of \(N^{3-} , O^{2-}\) and \(F^-\) are respectively :
- A \(1.71, 1.40\) and \(1.36\)
- B \(1.71, 1.36\) and \(1.40\)
- C \(1.36, 1.40\) and \(1.71\)
- D \(1.36, 1.71\) and \(1.40\)
Answer & Solution
Correct Answer
(A) \(1.71, 1.40\) and \(1.36\)
Step-by-step Solution
Detailed explanation
The ionic radii (in \(\dot{A}\) ) of \(N^{3-}, O^{2-}\) and \(F^{-}\) are respectively 1.71,1.40 and \(1.36 .\) \(N^{3-}, O^{2-}\) and \(F^{-}\) contains ten electrons each. Hence, they are isoelectronic species. For isoelectronic species, the nuclear charge increases on moving…
