which hypothesis of thomson's atomic model was later found to be not true by rutherford and why?

The "plum pudding" atomic model

J.J. Thomson suggested the "plum pudding" model in which the electrons and protons are uniformly mixed throughout the atom.

Rutherford discarded Thomson's hypothesis through the results he obtained in his "gold foil" experiment. According to Rutherford, if Thomson's model was correct, then the mass of the atom must extend throughout the atom, so if it triggered high-speed alpha particles to an atom, there would be very little room to deflect the particles. However, when he shot these particles at a thin film of gold atoms he observed that most of them went through the plate, but to their surprise, some alpha particles bounced almost directly backwards.

These deviations were not consistent with Thomson's model, so Rutherford was forced to discard Plum Pudding's model and reasoned that the only way alpha particles could deviate backward was if most of the mass in a atom was concentrated in a nucleus.

answer; i believe that the correct answer is (a) potassium(k)
