Essentially, if the electron tried to collapse close to the nucleus, we would know where it is located, which means its momentum would be uncertain, meaning it wouldn't *stay* close to the nucleus.
I don't understand how the bolded follows from Heisenberg's uncertainty. If I recall my chemistry correctly (probably not) isn't that just a limit of us measuring a particle's velocity or location, in that we can only measure one or the other? So how does that impact the location of the particle itself?
