Calculate for the **bond order of H _{2}**

*Step 1:* Calculate the total number of valence electrons present.

*Step 2:* Draw the molecular orbital diagram.

*Step 3:* Calculate the bond order of the molecule/ion. Recall that the formula for ** bond order** is:

$\overline{){\mathbf{B}}{\mathbf{.}}{\mathbf{O}}{\mathbf{.}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{1}}{\mathbf{2}}\left[{\mathbf{e}}^{\mathbf{-}}\mathbf{}\mathbf{in}\mathbf{}\mathbf{bonding}\mathbf{}\mathbf{MO}\mathbf{}\mathbf{-}\mathbf{}{\mathbf{e}}^{\mathbf{-}}\mathbf{}\mathbf{in}\mathbf{}\mathbf{antibonding}\mathbf{}\mathbf{MO}\right]}$

What is the bond order for H_{2}^{-} (hint: use MO theory)?

A. 0.5

B. 1

C. 3

D. 2

E. 1.5
