How does Rutherford鈥檚 model of the atom account for the back-scattering of alpha particles directed at the gold foil?

At the time of Rutherford鈥檚 gold-foil experiment, scientists knew that negatively charged electrons exist within the atom, but they did not know where the positive charge resides. What information about the positive charge was provided by Rutherford鈥檚 experiment?
