I have been spending time thinking about atoms with an open mind. In general, I am trying to think of atomic and molecular physics in terms of pure magnetism. I am going to explain my train of thought and, of course, I am receptive to the possibility that I am completely wrong on all counts. I truly wish to understand how things work.
A proton is positive, an electron is negative, and a neutron has a 'net-zero' charge. This is an axiom. However, the last bit, while true, is somewhat deceptive -- the implication being that it has no role in terms of magnetism. If a neutron is an electron and proton combined (as evident by mass comparison), then why is it not thought of as a bipolar magnet. A magnet has a net-zero charge as +1 + -1 = 0, but saying that a bipolar magnet has no magnetic effect is, obviously, a fallacy.
So let's assume that the neutron is a bipolar magnet for a bit here... Would the neutron not play a significant role in forming the shape of the atom? Is this what keeps the electrons and protons apart? Is this what creates all of the electron shells? Are neutrons the connectors when atoms form together into molecules? Do the number of neutrons directly affect the 'frequency' of the atoms?
Let's think about tritium, an isotope of hydrogen. With 2 'extra' neutrons, hydrogen becomes a 'radioactive' atom, giving off light. Is this because the frequency (as in hertz) is directly affected by the number of neutrons in the atom, in this case raising the frequency into the realm of visible light?
