Question: Which one of the following ions has the highest value of ionic radius
Options:
A) $ {{O}^{2-}} $
B) $ {{B}^{3+}} $
C) $ L{{i}^{+}} $
D) $ {{F}^{-}} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ {{O}^{-2}} $ has the highest value of ionic radii as this can be explained on the basis of $ Z/e{ \frac{\text{Nucleaus charge}}{No\text{. of electron}} } $ Whereas Z / e ration increases, the size decreases and when Z / e ration decreases the size increases.
