MCQ
For which of the following ionic species radius would be maximum ?
  • $C ^{4-}$
  • B
    $N ^{3-}$
  • C
    $O ^{2-}$
  • D
    $Mg ^{2+}$

Answer

Correct option: A.
$C ^{4-}$
a
Cation has small size than parent atom and anion has greater size than parent atom. The anion which have more negative charge have maximum ionic species radius. Thus the correct answer is $C ^{4-}$.
