### Step-by-Step Solution #### (i) What is a bonding molecular orbital? A bonding molecular orbital is a type of molecular orbital that is formed when two atomic orbitals combine in such a way that they create a region of increased electron density between the two nuclei of the atoms involved. This increased electron density leads to a stabilizing effect on the molecule, resulting in a lower energy state compared to the individual atomic orbitals from which it was formed. In summary, bonding molecular orbitals have lower energy than the atomic orbitals that combine to form them. #### (ii) Calculate the bond order (B.O.) of the `He₂` molecule. To calculate the bond order of the `He₂` molecule, we can use the formula: \[ ...
