Ionization Potential is currently defined by Quantum Physics as the amount of energy required to remove an electron from at atom.
This definition is based on concepts that differ from the single fundamental particle nucleus and single fundamental particle outer shell, found in Proto-Physics. With Quantum Physics there can be multiple electrons linked to the nucleus of an atom. This idea of multiple electrons in an element show that the definition of Ionization Potential in Proto-Physics is very different from the definition of Ionization Potential in Quantum Physics.
Proto-Physics defines Ionization Potential as: The energy required to move a single (¾c) Fundamental Particle, labeled the Proteon, from its location intersecting the single (¼c) Fundamenal Particle, labeled the Proteus, to the next referenced frame.
As you can see, based on this definition you will need to know: what Absolute Motion is; what a Proteus and Proteon are; and, have looked through the General Overview to gain a working knowledge of Proto-Physics. If you haven’t done that then what follows will be meaningless.
Ionization Potentials are a significant sign-post that the Proto-Physics model is the correct model for the atom. As was described in the General Overview, when a fundamental particle is accelerated to absolute motion ¼c(+xh), it bonds with its opposite fundamental particle moving at abolute motion ¾c(-xh).
