Bill: You what? An energy band? I thought you said that… How did the region convert to… Clark: Now with this model it is a piece of cake to show you how one energy level interacts with another. Bill: But how did the set of orbits that became an orbital which is really a region become an energy band that now forms a bond with another orbit? Clark: Oh dear. I fear that you may not have taken the prerequisites for this course. But let’s see if I can bring you up to speed. Let’s forget about the electron, about its orbit, about the orbital, and about the region. Just think of energy levels. So we have a nucleus surrounded by an energy level. And the energy level of an H-atom now interacts with the energy level of another H-atom to form a covalent bond. For example, water consists of an oxygen atom covalently bonded to two hydrogen atoms each of which is bound to another water molecule via hydrogen bonds.
