Scepti, how does your model of the atom explain the photoelectric effect?
If you don't know what it is, it's that if you shine UV light on a negatively charged piece of metal, it loses its negative charge. Same thing doesn't happen if the metal has a positive charge, or if the light is visible instead of UV. Why is this, what is special about a negative charge compared to a positive one.
This is an easy thing to test with a gold leaf electroscope, as the loss of charge causes the leaf to fall.
