Editing Two-body problem (section)

=== Inapplicability to atoms and subatomic particles ===

Although the two-body model treats the objects as point particles, classical mechanics only apply to systems of macroscopic scale. Most behavior of subatomic particles ''cannot'' be predicted under the classical assumptions underlying this article or using the mathematics here.

[[Electron]]s in an atom are sometimes described as "orbiting" its [[atomic nucleus|nucleus]], following an [[Bohr model|early conjecture]] of [[Niels Bohr]] (this is the source of the term "[[Atomic orbital|orbital]]"). However, electrons don't actually orbit nuclei in any meaningful sense, and [[quantum mechanics]] are necessary for any useful understanding of the electron's real behavior. Solving the classical two-body problem for an electron orbiting an atomic nucleus is misleading and does not produce many useful insights.
