Quantum Mechanical Treatment of the Valence Bond Theory

Quantum mechanical treatment of valence bond theory refers to the relationship established between the quantum mechanical theory and the valence bond theory to describe the chemical bonding in a particular molecule.

Question

At some point, the repulsive force grows so strong that
the atoms stop approach and begin to move apart,
causing the potential energy of the system to
decrease.
In the box below, explain this behavior: why do the
atoms repel and move apart? (Hint: think about the
electrons.)

After you watch for a few minutes, you'll notice that as
the atoms get very close to one another, the repulsive
force increases (symbolized by green force arrows that
point away from each other). This increase in the
repulsive force causes the potential energy of the
system (on the potential energy curve) to increase.
This is reproduced on the figure below, with specific
reference to the circled region.

Y Hint Lennard-Jones potential diagrams, also called intermolecular potential energy diagrams, illustrate the relationship between the potential energy of a molecule as the distance between the two nuclei changes. Select all of the true statements regarding Lennard-Jones potential diagrams. Once a balance is found between the attractive and repulsive forces, the outer orbitals are able to overlap, thereby allowing a bond to form. When the nuclei are infinitely far apart, the attractive forces between the nuclei are much greater than the repulsive forces between them, causing the potential energy to approach zero. When the nuclei are infinitely far apart, there is no repulsion or attraction between them; thus, the potential energy approaches zero. As the internuclear distance decreases, the nuclear and electrostatic repulsions increase significantly, causing a steep increase in potential energy. As the internuclear distance decreases, the attraction between the nuclei increases…
