Electrons moving at descrete orbits or shells ever collide or not. And what will happen if they collide with each other?
Depends what you mean by collide. Particles that repel each other can scatter off one-another, which is what must physicists would consider a collision.Electrons repel each other. Can not collide.
They can if they have opposite spin. Indeed, in certain electronic states there is an increase in the probability that two electrons will occupy the same position. Look up Fermi heap....and Pauli exclusion principle say that the electrons can not have same value of quantum numbers.
They can not be near each other
They don't move in the classical sense, like planets orbiting a star. They are in stationary states that are fully dependent on the other electrons being present. See also my post above.Electrons moving at descrete orbits or shells ever collide or not. And what will happen if they collide with each other?
You wrote that the fact that they have different quantum numbers means that "they can not be near each other," but they can have the same set of quantum numbers apart from spin, meaning that they have the same spatial wave function. I don't see therefore how this can lead to saying that they can't be near each other.The different spin is different quantum number.
This is that I wrote
