This makes sense as the "natural" state of an atom because if they held a net charge, they would be much more reactive and likely wouldn't remain in the same state for very long before interacting with something. So in most cases the charge of an atom is the same: zero. Understanding...

(40.1) is the potential energy of an atom. Therefore we can also state this particular law as: the density at any point is proportional to e^{−\text{the potential energy of each atom}/kT}. That may be an accident, i.e., may be true only for this particular case of a uniform ...
