In Rutherford's famous experiment, he shot heavy, fast moving, positive alpha particles at a thin gold foil. Based on Thomson's plum pudding model of the atom, what did Rutherford expect to happen, and why?

Rutherford expected for the alpha particles to go right through the gold foil since Thomson's plum pudding model showed that the positive energy was all over the atom with electrons randomly scattered all through empty space.

All the alpha particles would pass straight through the foil because of the even distribution of mass and charge throughout the atom.
