Some particles went straight through the foil and some were deflected at large angles, or even reflected backward. He assumed that the massive positively charged particles were repelled by a massive positive charge concentrated in a small region of the atom. He then concluded that an atom must have a nucleus.2.What is the main problem with a solar system model of the atom?a.The Bohr model of the atom successfully accounted for the line spectrum of hydrogen and provided an understandable mechanism for the emission of photonsby atoms. The model did not predict the spectra of any atom larger than hydrogen,and there were other limitations.3.Compare the size of an atom to the size of its nucleus.
