A) \[{{F}^{-}}\]
B) \[{{O}^{-2}}\]
C) \[A{{I}^{+3}}\]
D) \[{{N}^{-3}}\]
Correct Answer: D
Solution :
[d] Due to having three electrons atomic size increases. \[{{F}^{-}}=9+1=10\]electrons;\[{{O}^{-2}}=8+2=10\]electrons \[A{{I}^{+3}}=13-3=10\] electrons; \[{{N}^{3-}}=7+3=10{{e}^{-}}\] Because electrostatic force between nucleus and \[{{e}^{-}}\]cloud is least innitrogen.You need to login to perform this action.
