I know I've asked this before, but it keeps coming back to me, again and again:
Does a proton possess orbitals?
If you say I'm silly, then consider the thousands of Chemists worldwide who speak of the hydrogen ion (H+) as having orbitals.
Isn't a hydrogen ion a proton?
But isn't a proton a free particle by itself?
Quantum mechanics is just plain weird, period. :)
