If we are given two Hydrogen atoms, would the only difference between them would be their quantum state (Energy level or eigen value, and the corresponding Orbital or eigen state) and their location (say you are the origin and each of the Hydrogen atoms are located an arm's distance apart)
This leads to my next question which would be what's the difference between two Hydrogen atoms separated arm's distance and a Hydrogen molecule? Wouldn't the only difference be that they are located very close to each other?
