I am trying to to teach myself the basics of quantum mechanics and need a bit of help. I am a non-mathematician so go easy on the maths in any reply. I think I have understood the difference between the wave function, probability density and probability distribution in terms of describing atomic orbital structure. As far as I can see the probability distribution "spreads" the electron's properties through the orbital in line with levels of probability predicted by Schrodingers equation. Clearly this will apply to the electron's charge and mass, but does it also apply to its spin? Also, is there any other property of the electron that can be meaningfully distributed throughout the orbital with the probability distribution?
