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.

(got a 100%, 4/4 points)  

I personally think Thompson was most important. He discovered the electron and improved hugely on the atomic model with a positively charged sphere with negative electrons dispersed throughout, and the atom with a neutral charge.  

I think that without him, Rutherford wouldn't have done his gold foil experiment. Since Rutherford discovered the nucleus is positive, Bhor was able to find electrons have energy levels and that wouldn't have happened without Rutherford, who happened because of Thompson.  

the answer is b i think

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
