George is writing an essay about the role of observation and inference in the development of the atomic theory. He wants to explain why it was more difficult to observe the presence of neutrons in atoms. Which statements should he include in his essay? Choose the two statements that apply. A. While protons or electrons can be influenced by other charged particles, neutrons are not. B. It was difficult to observe that neutrons were different than protons because the two particles respond to charge in the same way. C. It was difficult to observe that neutrons were different than electrons because the two particles respond to charge in the same way. D. Neutrons are held tightly together with protons in the nucleus, so scientists could not observe the behavior of neutrons independently.
