    bohr also believed believed that there was a nucleus but he thought that the electrons did just float about inside an tom but orbit around the nucleus like planets around a sun in circular orbits

  • Schrodinger Model

    Schrodinger Model
    Schrodinger showed that electrons weren't orbiting around the nucleus but buzzing around like hyperactive flies sketching out different shapes and unlike bohr who called the circular path of the electrons orbit schrodinger called the buzzing orbital
