wavefunctions. Was this just a simplification, the truth being maybe that their wavefunctions can be

nonstationary for a little while, but soon decay into stationary ones? I’ve seen an answer, somewhere,

that if an orbital electron were not in a stationary state, its wavefunction would be a superposition of

wavefunctions one of which would be a wavefunction which would decay into a lower energy

wavefunction. However, if such a nonstationary wavefunction ψ

_{1}were equal to such a decay-prone ψ

_{2}+ some other ψ

_{3}, then any stationary ψ

_{4}would also be a superposition of wavefunctions one of which would be such a decay-prone wavefunction, e.g., ψ

_{4}= ψ

_{2}+ ψ

_{5}, where ψ

_{5}= ψ

_{4}- ψ

_{2}, so the same objection would apply to ψ

_{4}being a stable wavefunction of an orbital electron. What is the correct answer?
