Step 1:
The molecular geometry of F$_2^-$ is linear.
Since there is a negative charge on the molecule, we add one more electron to the total count. :::{.center} :::{.math} \chemfig{F-F} ::: :::
Step 2:
Calculate the bond order for the F-F bond. In the Lewis structure, there are two electron pairs shared between the two fluorine atoms. Therefore, the bond order for the F-F bond is: :::{.math} BO(F-F) = frac{Number\ of\ bonding\ electrons - Number\ of\ antibonding\ electrons}{2} = frac{2 - 0}{2} = 1 ::: The bond order for the F-F bond is 1, indicating a single bond.
Step 3:
In F$_2^-$, there are 14 valence electrons (7 from each fluorine atom and 1 excess electron).

Step 4:
Therefore, F$_2^-$ is paramagnetic.
According to the magnetic property rules, a molecule with an odd number of unpaired electrons is paramagnetic. **
Final Answer
- Bond order of F-F bond: 1 - HOMO: Bonding molecular orbital - LUMO: Antibonding molecular orbital - Magnetic properties: Paramagnetic
