Given species N^{3-} , O ^{2- } , F^- , Na ^+ , Mg ^{2+ }, Al ^{3+} are isoelectronic species as they have the same number of electrons i.e., 10 electrons.

N^{3-}has\ 7+3 =10\ electrons. 

O^{2-}has\ 8+2 =10\ electrons.

F^{-}has\ 9+1 =10\ electrons.

Na^{+}has\ 11-1 =10\ electrons.

Mg^{2+}has\ 12-2 =10\ electrons.

Al^{3+}has\ 13-3 =10\ electrons.
