  • Rutherford's Nuclear Atom

    Rutherford's Nuclear Atom
    Found by Ernest Ruterford.The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun.
  • Solar System Model

    Solar System Model
    Niels Bohr proposed the "Solar System" model of the atom, also known as the Rutherford-Bohr model. The model is similar to a solar system: electrons revolve around the nucleus like planets revolving around the sun. However, instead of gravity being the force of attraction, electrostatic forces keep the electrons in orbit.
