EDIT 1: Many people are recommending that the question Do electrons really perform instantaneous quantum leaps? is very similar to mine. However, that question is very specific to quantum leaps. I am also asking about a possible relation to QFT and the all-fields model.
Having learned that electrons can move from one energy level to another by transmitting or taking in energy, I am interested in knowing how exactly do they "jump" from one level to another. Do the electrons move as a particle or as a wave through energy levels. Because if they move as a particle, the distance and space between the electron shells must be covered, so do electrons move through the orbitals as a whole particle? Or do they move like a wave, because electrons exhibit wave-particle duality? Also, is the "jump" from one energy level to another instantaneous or is there a transmission delay? Because from what I have read, it seems that an instantaneous transmission has not been proved, whereas a delayed transmission by direct action-at-a-distance theory has been proven by experiments. Also, in a quantum mechanics explanation of electron transmission, I learned that the electron is destroyed in the original orbital, then recreated in another orbital, and the result also releases a photon. I thought that matter could not be created nor destroyed.
Furthermore, could it be possible that if the field model is used, it could possibly simplify the matter? If the field model is used, then would it be right to assume that the electron field is part of the shells/energy level where the electrons are, because electrons are just vibrations of the electron field and for them to be "created" they must come from a field? If we do assume that the electron field is present, then can we not say that since the field is able to occupy the space in which the distinct energy levels are in, then an electron's energy in one energy level can be absorbed by the field and then "moved"/transmitted to another energy level, through the use of the field? And this would be done by the energy traveling from one part of the field which is at a certain energy level to another, and then the energy can cause a vibration which will "pop-out" an electron at the new place in the field which is the new energy level.
Please let me know if any of my logic or understanding of the topic is flawed. I am very interested in getting to know everyone's take on this.
