A similar process happened at about 1 second for electrons and positrons.

The best I can do is give you an analogy to the more familiar theory for electrons.

There exist only limited possible states of energy for electrons, atoms and molecules.

However, this is not because the tires ground you, but rather they serve as an insulation - a more difficult path for electrons to run.

Mobility is also different for electrons and holes in a given semiconductor.

Single lenses as known from photonics are not easily available for electrons.

If the two batteries are not connected together, there is no way for electrons in one battery to get to the other.

It would take half an hour for electrons to cross a 10-foot room at this rate.

A similar thing is true for electrons in atoms and molecules.

Simply defined as the different states of potential energy for electrons in an atom.
