###### FREE Expert Solution

We are being asked to draw the MO energy diagram of Li2+ and Li2- then predict which will exist in the gas phase.

We will 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:
