Explain in short: $MO$ occupancy and molecular properties for $B_2, C_2, N_2, O_2, F_2, Ne_2$.

(N/A) The molecular orbital $(MO)$ occupancy,bond order,magnetic properties,and valence electron configurations for the homonuclear diatomic molecules $B_2, C_2, N_2, O_2, F_2,$ and $Ne_2$ are summarized in the following table:
| Molecule | Valence Electron Configuration | Bond Order | Magnetic Property |
| :--- | :--- | :--- | :--- |
| $B_2$ | $(\sigma_{2s})^2 (\sigma^*_{2s})^2 (\pi_{2p})^2$ | $1$ | Paramagnetic |
| $C_2$ | $(\sigma_{2s})^2 (\sigma^*_{2s})^2 (\pi_{2p})^4$ | $2$ | Diamagnetic |
| $N_2$ | $(\sigma_{2s})^2 (\sigma^*_{2s})^2 (\pi_{2p})^4 (\sigma_{2p})^2$ | $3$ | Diamagnetic |
| $O_2$ | $(\sigma_{2s})^2 (\sigma^*_{2s})^2 (\sigma_{2p})^2 (\pi_{2p})^4 (\pi^*_{2p})^2$ | $2$ | Paramagnetic |
| $F_2$ | $(\sigma_{2s})^2 (\sigma^*_{2s})^2 (\sigma_{2p})^2 (\pi_{2p})^4 (\pi^*_{2p})^4$ | $1$ | Diamagnetic |
| $Ne_2$ | $(\sigma_{2s})^2 (\sigma^*_{2s})^2 (\sigma_{2p})^2 (\pi_{2p})^4 (\pi^*_{2p})^4 (\sigma^*_{2p})^2$ | $0$ | Diamagnetic |
