I would go for the Rutherford Model:


In this model the atom is described as a planetary system with a central massive (and concentrated) positive charge, the nucleus, and orbiting around it (at various radial distances) the planet-like negative charges, the electrons.

Most of the internal part of the atom is empty space and the radial disposition of the electron "planets" would account for internal structure and energy of the atom as a whole.

The problem with this model is that, classically, the orbiting electrons (charged particles accelerated) would radiate continuously energy (e-m radiation, as, for example, in an antenna) rapidly falling into the, basically, there shouldn´t be any more atoms around!

This problem will be solved by Bohr introducing stable orbits where electrons do not radiate!
