First of all I would like to thank everyone for their replies. I thought I would be lucky to get one or two replies. This was a great response. Thank you. To answer the general question of what level I am at. I am into natural philosophy so I do not have a strong background in mathematics. I am intensely interested in physics and how things work mechanically speaking. I am open to all perspectives but I do have my own opinions on how things in the Universe work. These statements should be a good clue to my style of thinking. I did look into the Bohr model already and found that this was abandoned as it did not work for more complicated atoms. I still think this method has great promise and can be applied to more complicated systems. What I believe is missing is that the equations need to evolve to more complex formulations in order to include additional interactions that effect the electrons and the overall atomic systems.
I ask this question in order to see what the latest thinking is on this topic and because I have my own idea on what the answer should be. Ultimately I am interested in knowing and understanding the answer to this question. I was not able to find on the Internet a definitive answer to this topic.
So far what I am getting from the comments is that the exact answer to this question is not known for sure. There are at least 3 various perspectives.
1. No measurements have been made on individual electrons outside of an atom or at different orbitals.
2. An assumption that if different electrons have different masses they would have different chemical and physical properties. I think that I may agree with that and so I suspect that electrons do have different properties when in different orbitals. This is what I think that I understand about electrons. Please correct me if I have something wrong.
A. Electrons go to higher orbitals when they absorb photons.
B. Electrons become more energetic as they absorb photons.
C. Electrons can absorb more than one photon.
D. Electrons loose energy when they emit photons.
E. Electrons drop to lower orbitals when they emit photons.
F. If Electrons gain and loose energy then their velocity and mass should change as a result of the energy gain or loss.
My thinking that caused my question
A. If photons do become more energetic when they absorb a photon then this must mean they have undergone a transformation because of the addition of the photon.
B. If the photon does in fact increase in energy then the velocity at which the photon travels at must increase in that orbital. Has this ever been measured or looked for.
C. Since I believe that a electron has a particular velocity then an electron has a path. At this point all Quantum Mechanics people may want to argue against such a notion as they believe that particles do not have individual paths or velocities. But in order to determine the possibility of electrons having different masses I think that a classical approach to this problem would be best suited for answering the question and or determining an experiment that could answer my question.
D. I believe that classical approach would be the best approach since QM has provided no solution for the origin of mass so until such a time, I believe that QM mathematics could only be utilized to a limited extent by including QM constants and quantized values in differential equations.
3. The next comment... "The change in the mass of the system composed of the nucleus and the electrons is a relativistic effect which is not included in textbook solutions of the hydrogen atom."
That is very interesting, perhaps it should be included. What if the relativistic effect is in fact the complete and central cause of the emergence of the mass field. I think that this is a strong possibility. I believe that there is a great deal of evidence to support such a claim. Just my opinion.
These additional comments hopefully explains why I am asking about such a specific detail. I want to know what main stream physics knows about my question. If someone knows the answer, for sure, one way or the other. I would really be interested in knowing the exact details and interpretation and meaning of those details. If someone knows of an experiment that has been performed to determine if electrons have different properties in different orbitals I would love to know the details of the results.
