11.1 – What a Bonding Theory Should Do
As the two H atoms approach each other, three types of interactions occur:
1. Each electron is attracted to the other nucleus
2. The electrons repel each other
3. The two nuclei repel each other
~ The potential energy corresponds to the negative of the bond-dissociation energy.
The strength of the Lewis structure is its ability to be written with ease, however it is
unable to demonstrate the molecular shape of the molecule.
Covalent Bonding: the sharing of electrons between atoms to achieve greater stability
Nucleus has a positive point charge; electron cloud is present (determined by the
If H atoms are far apart, there are no interactions:
As two lone H atoms move closer together, there are interactions:
Attraction from the electron cloud, results in an repulsion
