J. J. Thomson discovered the electron in 1897. In 1904, he proposed a model of an atom, describing that there was an equal distribution of negative and positive charges throughout the atom. In 1909, Ernest Rutherford tested J. J. Thomsonâs model by shooting positive particles at gold foil. Based on Thomson's model, it was predicted that the particles would fly through the foil with a small amount deflected back. Analyzing the results, Rutherford discovered that more of the particles bounced back than expected. Which of the following best explains how the results of Rutherfordâs experiment affected Thomsonâs widely-accepted atomic model?
A. Rutherfordâs results were invalidated and discarded because Thomsonâs model was correct.
B. Rutherfordâs results supported parts of Thomson's model, but also provided new data and interpretations.
C. Rutherfordâs results suggested that the model proposed by Thomson was based on false research and required a change in his hypothesis.
D. Rutherfordâs results supported Thomsonâs model that there was a negative core surrounded by positive charges and caused a modification in the overall atomic theory.
