- No reference to wavefunctions, which is precisely what an orbital is!
- Implication that filling all orbitals is stable, in which case everything should really have infinite electrons so that it can fill its infinite orbitals.
- "Energy state" instead of "principal quantum number"
- Bohr model terminology: "volume within which the electron can stably orbit the nucleus"
- 90% probability is an arbitrary definition, not arising from Heisenberg uncertainty principle
- Implication that the angular momentum quantum number is $l = 1$ for an s-orbital
I plan on rewriting it some time soonTM (the exact time depends on how motivated I am). However, I do want to make sure I capture the scope of this tag correctly.
Since we already have molecular-orbital-theory, can I assume that orbitals only refers to atomic orbitals? The existing tag wiki strongly suggests this, but I am hesitant to do this, because one of the top questions is about Kohn-Sham orbitals, which are obviously not atomic orbitals, but do not quite belong under molecular-orbital-theory either.
If not, what should the exact scope be described as?
