MCQ
The isoelectronic set of ions is
  • A
    $Li^, Na^+, O^{2-}$ and $F^-$
  • B
    $F^-, Li^+, Na^+$ and $Mg^{2+}$
  • ✓
    $N^{3-}, O^{2-}, F^-$ and $Na^+$
  • D
    $N^{3-}, Li^+, Mg^{2+}$ and $O^{2-}$
✓

Answer

Correct option: C.
$N^{3-}, O^{2-}, F^-$ and $Na^+$
c
In this we have to choose isoelectronic set of ions: Isoelectronic species are those which have same no. of electron in total, so option $3$ is correct
