Isoelectronic species are those species that have the same 

number of electrons.

\therefore N^{3-}, O^{2-},F^{-} \: \: and \: \: Na^{+} are isoelectronic species & have 

same number of electrons equal to 10.

\therefore option (1) is correct.


Option 1)

N^{3-}, O^{2-},F^{-} \: \: and \: \: Na^{+}

Option 2)

N^{3-}, Li^{+},Mg^{2+} \: \: and \: \: O^{2-}

Option 3)

F^{-},Li^{+}, Na^{+} \: \: and \: \: Mg^{2+}

Option 4)

Li^{+},Na^{+},O^{2-} \: \: and \: \:F^{-}
