Classification Of Elements And Periodicity In Properties Question 17
Question: The ionic radii of $ {{N}^{3-}} $ , $ {{O}^{2-}} $ , $ {{F}^{-}} $ and $ N{{a}^{+}} $ follow the order [MP PET/PMT 1998; MP PMT 2000]
Options:
A) $ {{N}^{3-}}>{{O}^{2-}}>{{F}^{-}}>N{{a}^{+}} $
B) $ {{N}^{3-}}>N{{a}^{+}}>{{O}^{2-}}>{{F}^{-}} $
C) $ N{{a}^{+}}>{{O}^{2-}}>{{N}^{3-}}>{{F}^{-}} $
D) $ {{O}^{2-}}>{{F}^{-}}>N{{a}^{+}}>{{N}^{3-}} $
Show Answer
Answer:
Correct Answer: A
Solution:
As effective nuclear charge on $ N{{a}^{+}} $ is maximum. It has smallest size.
