The general sequence of the energy level of molecular orbitals for nitrogen is:

The molecular orbitals in the sequence of their energy levels for the given molecules are given below:

Since the bond order is 3, N₂ has a triple bond.

F₂ = σ 1s², σ ^* 1s², σ 2s², σ^* 2s², σ 2p_x², π 2p_x² = π2p_y²

The molecular orbital of Fluorine is given

The bond order of F₂ =

Thus, when bond order is 1, the number of bonds is also 1.

Ne₂ = σ 1s², σ ^* 1s², σ 2s², σ^* 2s², σ 2p_x², π 2p_x² = π2p_y², π^*2p_x² = π^*2p_y²

The bond order of Ne₂==0

Thus, Ne₂ has no bond.
