The uncertainty principle. The electron has already radiated away as much
energy as it can, it has fallen into the proton as far as it can go. With
Coulomb's law and the uncertainty principle you can derive the size of a
hydrogen atom.

That's directly related to the electron being a wave. Uncertainty
principles aren't unique to quantum mechanics, every wave mechanics has
them, e.g. the duration versus frequency spread of a noise like a hand
clap or a pure tone. Quantum mechanics is (for the most part) just
another wave mechanics.
