An object with increased energetic field density rises in a gravitational field (it has more momentum) while an object with a weak field (less momentum) falls in a gravitational field. As the field density increases, falling objects accelerate, while rising objects decelerate as the field density of the surrounding field decreases.

When energy is added to an atom, it becomes to dense and an object is expelled from the spatial energy field of the atom. Alternatively we could say that an 'electron' became to dense and was expelled from the field, which would then be exactly equivalent to gravitation. An ion can be thought as being 'negatively charged' (to much space, not enough energy) and therefore an 'ion is not dense enough' and therefore can absorb an 'electron'. Here we assume that an ejected electron experiences a sudden burst of velocity and then decelerates, while a received electron accelerates (a behavior similar to that of objects rising and falling in a gravitational field).
