The torus does not seem to be stable at all, if the nucleus is still the center of attention. It is not. The tight loop of electron orbit is.
It is the nucleus that is trapped in the \(B\) orbits. Not the electron being pulled and restricted by the nucleus.
The electron will not collapse to a lower orbit because of the light speed limit. Drag provides the centripetal force not electrostatic attraction.
This means electrons can be in orbit without a nucleus momentarily. And it is the \(B\) orbit that captures and hold a nucleus.
I think I have the whole picture. Of covalent bonds and ionic bonds, stable 8 configurations...
The next electron that enters the picture fills up the torus! 8 electrons. After which electronic shells begin to form and as a whole behave like a partially charged nucleus. Then the torus configuration starts over again.
The spherical electronic shells form ionic bonds. For the torus, the electron's orbit chain up and form stronger covalent bonds.
I have got it! Nobel prize!
