It doesn't, though. In a Uranium atom, for example, there are 92 electrons, but there really are not 92 individual electrons at all. In fact, there is NO individual electron in that system. There is simply a system composed of 92 electrons but no single identifiable negative charge entity exists...
I think people are just stuck thinking of the “solid particle” model, they can’t conceive that we are really talking about waves here.
What is one standing wave versus ninety-two standing waves, if they are superimposed on top of each other, or in close proximity? You can’t lay your finger on any physical substance and say “there is the wave”, it’s just an oscillation in the medium. If you have more than one oscillation pattern, there is still nothing to point at, even if you have ninety-two of them.
