3. 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. thomson's 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 rutherford's experiment affected
thomson's widely-accepted atomic model?
