Which Scientists influenced this Scientists work? Why? I believe that the scientists before Rutherford would have inspired him to investigate in Atoms. This may of occurred because there was a conspiracy towards the atoms due to nobody actually seeing them.

What part of the Atomic Theory did they investigate? Ernest Rutherford was responsible for a many different discoveries such as radioactivity and nuclear physics. He discovered alpha and beta rays, found the laws of radioactive decay, and identified alpha particles as helium nuclei. Most important, he postulated the nuclear structure of the atom this structure was known as Rutherford model. Rutherford overturned Thomson 's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny, 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. Ernest Rutherford publishes his atomic theory describing the atom as having a central positive nucleus surrounded by negative orbiting electrons. This model suggested that most of the mass of the atom was contained in the small nucleus, and that the rest of the atom was mostly empty space.
