    Rutherford scattering experiments - Wikipedia

    • Thomson's model of the atom The prevailing model of atomic structure before Rutherford's experiments was devised by J. J. Thomson. Thomson had discovered the electron through his work on cathode rays and proposed that they existed within atoms, and an electric current is electrons hopping from one atom to an adjacent one in a series. There logically ha… See more

    Overview

    The Rutherford scattering experiments were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated. They deduced thi… See more

    Experiments

    Rutherford's first steps towards his discovery of the nature of the atom came from his work to understand alpha particles. In 1906, Rutherford noticed that alpha particles passing through sheets of mica were deflec… See more

    Rutherford's scattering model

    Rutherford begins his 1911 paper with a discussion of Thomson's results on scattering of beta particles, a form of radioactivity that results in high velocity electrons. Thomson's model had electrons circulating i… See more

    Limitations to Rutherford's scattering formula

    In 1919 Rutherford analyzed alpha particle scattering from hydrogen atoms, showing the limits of the 1911 formula even with corrections for reduced mass. Similar issues with smaller deviations for helium, magnesium… See more
