After he conducted cathode ray tube experiments proving the existence of negatively charged particles we now call electrons, Thomson proposed a model of the atom called the plum pudding model. Describe how Rutherford's gold foil experiment disproved Thomson's model. (all that apply)
a. If the Thomson model was correct, the alpha particles bombarding the gold foil in Rutherford's experiment would have all passed through undeflected.
b. In Thomson's plum pudding model, the atom was thought to consist of electrons scattered throughout a sphere of positive charge.
c. If the Thomson model was correct, the beta particles bombarding the gold foil in Rutherford's experiment would have all passed through undeflected.
d. In Thomson's plum pudding model, the atom was thought to consist of protons scattered throughout a sphere of negative charge.
e. In Rutherford's experiment, some of the alpha particles were deflected indicating the model needed a dense core as a nucleus.
f. In Rutherford's experiment, some of the beta particles were deflected indicating the model needed a dense core as a nucleus.
