Re: Acceleration of charge

Thanks. The reply by Tom Roberts and PD's reference to a recent AJP
article gave me all I needed. I would like to append one more question
to this thread.

If we consider an atom like Hydrogen, then the positive charge is
essentially concentrated in an interior nucleus and the electrons are
spread out in a thin uniform shell, from the point of view of classical
Maxwell's equations. If this atom is now placed in orbit around a point
mass the charges are being accelerated and hence should "radiate"
(modulo Tom's criticism of the word in the previous question). In fact
the proton and "smeared" electron should both radiate. If they were on
top of each other there would be no net radiation. But in this case
they are not. So will the Hydrogen atom radiate energy and hence spin
into the center? If the spherical symmetry of the Hyrdogen atom
prevents it from radiating what about a molecule like ammonia or water?
Thanks,
