Exploring Atomic Partons: Probability Plot for n=2, l=1, m=0 in Hydrogen

[Bob_for_short]

Let us consider an atomic orbital, for example n=2, l=1, m=0 in Hydrogen. The probability plot is given in the figure attached. This picture can be obtained experimentally: via X-ray and elastic electron scattering. Each negative sub-cloud carries a fractional charge. Fortunately, we have quantum mechanics to explain it but if the scattering experiments had been carried out before QM establishing, would we have advanced a parton-like hypothesis for atoms?

I do not know if it would be correct to consider each sub-cloud as an "elementary" particle with a fractional charge. Do you?

It's no more correct than to say that the left half of the 1s distribution has charge 1/2 and the right half also has charge 1/2.

I did not understand your phrase.

I wanted to say that considering each sub-cloud as originating from some elementary particles (atomic partons) would be misleading.

 

[Vanadium 50]

Dividing the orbital into "subclouds" is imposing your sense of pattern recognition on it. There's nothing whatsoever like a particle with fractional charge.

 

[Bob_for_short]

This pattern can be observed experimentally, can't it?

Why we advance a parton model for protons? Following the experimental pattern.

Bob, this is silly. An electron has charge -1. The fact that it has a probability distribution doesn't mean anything has a factional charge.

Bob, this is silly. An electron has charge -1. The fact that it has a probability distribution doesn't mean anything has a factional charge.

I completely agree with you. Concerning atoms, I speak of a purely hypothetical situation. But it is similar to the deep inelastic scattering interpretation, isn't it?

 

[Vanadium 50]

No Bob, it has nothing whatsoever to do with fractional charge and DIS.

I have answered your question four times now. This thread is done.
