Classification Of Elements And Periodicity In Properties Question 127
Question: The order of the magnitude of ionic radii of ions $ {{N}^{3-}},{{O}^{2-}} $ and $ {{F}^{-}} $ is [MP PMT 1996]
Options:
A) $ {{N}^{3-}}>{{O}^{2-}}>{{F}^{-}} $
B) $ {{N}^{3-}}<{{O}^{2-}}<{{F}^{-}} $
C) $ {{N}^{3-}}>{{O}^{2-}}>{{F}^{-}} $
D) $ {{N}^{3-}}<{{O}^{2-}}>{{F}^{-}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ {{N}^{3-}}>{{O}^{2-}}>{{F}^{-}} $ . All are isoelectronic but nuclear charge per electron is highest for $ {{F}^{-}} $ , so it has smallest size.
