The bond order of $He_2^+$ molecule ion is

Group the following molecules/ions according to their bond order: $O_2^{2-}, Li_2, O_2^{2+}, F_2, N_2, He_2^{2+}$.

Bond order normally gives an idea of the stability of a molecular species. All the molecules,namely $H_2$,$Li_2$,and $B_2$,have the same bond order,yet they are not equally stable. Their stability order is:

Distinguish between bonding molecular orbitals and antibonding molecular orbitals.

The bond order is maximum in

Give the electron configuration,magnetic property,bond order,and energy diagram for the Nitrogen $(N_{2})$ molecule.
