The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models. The … WebRutherford reasoned that if Thomson’s model was correct then the mass of the atom was spread out throughout the atom. Then, if he shot high velocity alpha particles (helium nuclei) at an atom then there would be very little to deflect the alpha particles. Was Rutherford’s model incomplete or incorrect? – Additional Questions

In addition, Rutherford devised an experiment in which alpha particles emitted by a radioactive element served as probes into the world of unseen atomic structure. consumer reports big and tall office chairs
