🤓 Based on our data, we think this question is relevant for Professor Sandusky's class at URI.

We’re being asked to **determine the bond order** of **Be _{2}^{-}**. For this, we need to do the following steps:

*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:

$\overline{){\mathbf{Bond}}{\mathbf{}}{\mathbf{Order}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{1}}{\mathbf{2}}\mathbf{[}\mathbf{\#}\mathbf{}\mathbf{of}\mathbf{}{\mathbf{e}}^{\mathbf{-}}\mathbf{}\mathbf{in}\mathbf{}\mathbf{bonding}\mathbf{}\mathbf{MO}\mathbf{}\mathbf{-}\mathbf{}\mathbf{\#}\mathbf{}\mathbf{of}\mathbf{}{\mathbf{e}}^{\mathbf{-}}\mathbf{}\mathbf{in}\mathbf{}\mathbf{antibonding}\mathbf{}\mathbf{MO}\mathbf{]}}$

What is the bond order of Be_{2} ^{−}?
