Recall that the bond order tells us the strength and length of a bond: a higher bond order means the bond is stronger and shorter.

higher bond orderhigher bond strength → more stable

We can calculate for the bond order using:

bonding MOs → without an asterisk (e.g., σ1s)
antibonding MOs those with an asterisk (e.g., σ1s*)

a. F22+

Group            Valence Electrons
F        7A                   2 × 7 e14 e
From +2 charge:        – 2 e
Total:  12 valence e Bond Order = 2.0

b. Ne22+

Group            Valence Electrons
Ne      8A                   2 × 8 e16 e
From +2 charge:        – 2 e
Total:  14 valence e Bond Order = 1.0

c. F22-

Group            Valence Electrons
F        7A                   2 × 7 e14 e
From charge:        +2 e
Total:  16 valence e 79% (479 ratings) ###### Problem Details
