160861 What is the order of stability of $\mathrm{N}_2$ and its ions :

1 $\mathrm{N}_2>\mathrm{N}_2^{+} \approx \mathrm{N}_2^{-}>\mathrm{N}_2^{2-}$

2 $\mathrm{N}_2{ }^{+}>\mathrm{N}_2->\mathrm{N}_2>\mathrm{N}_2{ }^{2-}$

3 $\mathrm{N}_2^{-}>\mathrm{N}_2^{+}>\mathrm{N}_2>\mathrm{N}_2^{2-}$

4 $\mathrm{N}_2{ }^{2-}>\mathrm{N}_2^{-} \approx \mathrm{N}_2^{+}>\mathrm{N}_2$
