Answer:
The present day model shows a nucleus composed of protons and neutrons with cloud-like spheres of different diameters surrounding the nucleus to represent the energy levels of the electrons in the atom. Rutherford's model shows electrons orbiting the nucleus along fixed, but similar- diameter circular paths.
Both models show the composition of the nucleus at the center of the atom and the much smaller electrons at some distance from the nucleus.
Explanation:
Neither of the models does a good job of representing the relative size differences of the protons, neutrons and electrons, or the distance between the nucleus and the "electron clouds."
