Question:
Use molecular orbital theory to explain why the Be2 molecule does not exist.

Answer:

The electronic configuration of Beryllium is 1s² 2s².

From the electronic configuration it is clear that there is no singly filled atomic orbital present in beryllium.

Without the half- filled orbital, the overlapping is not possible, therefore Be2 molecule does not exist.
