Consider the work of Thomson, Rutherford, and Bohr. In your opinion, which was the most important and why? Be sure to state what your selected person discovered and how it contributed to the model of the atom.

Thomas was most important because he discovered the electron and proposed the plum pudding model of the atom where there's a dispersed positive charge with electrons sitting in it. He was most important because without him Rutherford wouldn't have done his gold foil experiment to test that alpha particles pass through or atoms and discover the positive nucleus, and then bohr wouldn't have figured out that electrons have energy levels without Rutherford discovery of the positive nucleus
