What did Thomson contribute to the model of the atom?
In 1897, J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas.Click to see full answer.

In addition, he also studied positively charged particles in neon gas.Click to see full answer. Likewise, people ask, what did Rutherford contribute to the model of the atom?Rutherford overturned Thomson’s model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.Secondly, what did Thomson discover? Electron Isotope Subatomic particle Similarly one may ask, what was missing in Thomson’s model of the atom? Thomson’s atomic model failed to explain how the positive charge holds on the electrons inside the atom. It also failed to explain an atom’s stability. The theory did not mention anything about the nucleus of an atom. It was unable to explain the scattering experiment of Rutherford.What did Rutherford discover that Thomson did not understand?A) that an atom’s electrons took up as much space as its nucleus. B)that atoms were too small to affect alpha particles. C) that electrons were much smaller than alpha particles.
