    Rutherford’s Nuclear Model of Atom:b

    • Geiger and Marsden carried out few experiments on the advice of Rutherford
    • On a very thin gold foil, highly energetic ray of α-particles(that are positively charged with energy of 5.5MeV)was incident
    • Scattered α-particles when strike zinc sulphide screen(surrounding the thin gold foil) produced light flashes(scintillations) which were observed via detector(microscope)
    • Electrons and protons are bound together by electrostatic forces of attraction and atom, as a whole is electrically neutral.
    • Rutherford was the first to discover that atom has a nucleus and so his model was called as Rutherford’s nuclear model of atom.
