The correct answer is: $\mathrm{N}_2^{2-} < \mathrm{N}_2^{-} < \mathrm{N}_2$
$$
\begin{aligned}
& \mathrm{N}_2=14 \mathrm{e}=\mathrm{B} \cdot \mathrm{O} \cdot=3 \\
& \mathrm{~N}_2^{-}=15 \mathrm{e}=\mathrm{B} \cdot O \cdot=2.5 \\
& \mathrm{~N}_2^{2-}=16 \mathrm{e}=\mathrm{B} \cdot \mathrm{O} \cdot=2
\end{aligned}
$$
