Describe 3 experiments, run prior to 1930, and the types of energies/particles used to probe the structure of the atom. What did each experiment investigate? Include the names of the scientists associated with each experiment in your answer
Would this be right?
Prior to 1930, radioactivity was discovered with three different types: alpha, beta, and gamma particles. With alpha particles, Rutherford and Chadwick were able to discover two parts of the atom: the nucleus and neutron, respectively. Rutherford did the gold foil experiment, with Chadwick doing a similar one. Thomson founded the electron with the cathode ray tube, powered by a high electrical voltage.

Good except the first sentence is misleading. Those experiments did not discover "radioactivity". They were studies into the structure of matter as described in the problem statement. For discovery of radioactivity see "Madame Curie". for example : http://www.sciencemuseum.org.uk/onlinestuff/stories/marie_curie_and_the_history_of_radioactivity.aspx
If I were to rewrite this paragraph, should I scratch the first sentence and add it to the bottom with a bit of change in it?
