  1. Rutherford model

    The gold-foil experiment showed that the atom consists of a small, massive, positively charged nucleus with the negatively charged electrons being at a great distance from the centre. Niels Bohr built upon Rutherford's model to make his own. In Bohr's model the orbits of the electrons were explained by quantum mechanics.

  2. Bohr Model of the Atom

    The Bohr model or Rutherford-Bohr model of the atom is a cake or planetary model that describes the structure of atoms mainly in terms of quantum theory. It's called a planetary or cake model because electrons orbit the atomic nucleus like planets orbit the Sun, while the circular electron orbits form shells, like the layers of a cake. Danish ...

  3. Rutherford model

    The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger-Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson 's plum pudding model of the atom was incorrect. Rutherford's new model [1] for the atom, based on the experimental results, contained new ...

  4. Bohr Model of the Atom

    The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. ... The Bohr Model is a planetary model in which the negatively charged electrons orbit a small, positively charged nucleus similar to the planets orbiting the sun ...

  5. Postulates of Rutherford's atomic model: The planetary model

    Rutherford's atomic model or planetary model of the atom is a model proposed by Ernest Rutherford. In 1909 the Geiger and Marsden experiment was performed, also known as the Rutherford experiment, as it was led by Rutherford himself. The Rutherford scattering observed in the investigation suggested that the early "Panettone" and "Saturnian ...

  6. Atomic flashback: A century of the Bohr model

    Bohr, one of the pioneers of quantum theory, had taken the atomic model presented a few years earlier by physicist Ernest Rutherford and given it a quantum twist. Rutherford had made the startling discovery that most of the atom is empty space. The vast majority of its mass is located in a positively charged central nucleus, which is 10,000 ...

  7. The Bohr Model of the Atom

    In 1913, Danish physicist Niels Bohr applied Max Planck's quantum theory to the nuclear atom of Ernest Rutherford, thus formulating the well-known planetary model of the atom, wherein electrons orbit a central nucleus in well-defined levels of energy ().Note that Bohr stated that electrons in the atom follow elliptical orbits (not circles as is often pictured).

  8. Atom

    Atom - Nuclear Model, Rutherford, Particles: Rutherford overturned Thomson's model in 1911 with his famous gold-foil experiment, in which he demonstrated that the atom has a tiny, massive nucleus. Five years earlier Rutherford had noticed that alpha particles beamed through a hole onto a photographic plate would make a sharp-edged picture, while alpha particles beamed through a sheet of mica ...

  9. Niels Bohr and The Planetary Model of the Atom

    In 1913 Bohr published a theory about the structure of the atom based on an earlier theory of Rutherford's. Rutherford had shown that the atom consisted of a positively charged nucleus, with negatively charged electrons in orbit around it. Bohr expanded upon this theory by proposing that electrons travel only in certain successively larger ...

  10. Bohr model

    Bohr model, description of the structure of atoms, especially that of hydrogen, proposed (1913) by the Danish physicist Niels Bohr. 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 Bohr model and ...

  11. 20.3: Bohr's Atomic Model

    The popular theory of atomic structure at the time of Rutherford's experiment was the "plum pudding model." This theory held that the negatively charged electrons in an atom were floating in a sea of positive charge (the electrons playing the role of plums in a bowl of plum pudding). ... The planetary model offered no explanation for the ...

  12. Bohr model

    The Bohr model is a relatively primitive model of the hydrogen atom, compared to the valence shell model. As a theory, ... Atomic orbitals within shells did not exist at the time of his planetary model. Bohr explains in Part 3 of his famous 1913 paper that the maximum electrons in a shell is eight, writing: "We see, ...

  13. The Planetary Model of the Atom

    The Planetary Model of the Atom. Ernest Rutherford. The stage was now set for the unexpected discovery that the positively charged part of the atom was a tiny, dense lump at the atom's center rather than the "cookie dough" of the raisin cookie model. By 1909, Rutherford was an established professor, and had students working under him.

  14. 22.1 The Structure of the Atom

    The planetary model of the atom pictures low-mass electrons orbiting a large-mass nucleus. The sizes of the electron orbits are large compared with the size of the nucleus, and most of the atom is a vacuum. ... Limits of Bohr's Theory and the Quantum Model of the Atom. There are limits to Bohr's theory. It does not account for the ...

  15. Bohr Model of the Atom

    The Bohr Model is a model of an atom. The model was proposed by physicist Niels Bohr in 1913. In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells. The model is also referred to as the planetary model of an atom. The electrons orbit around the nucleus similar to how planets orbit around the sun.

  16. Rutherford Atomic Model: Experiment, Postulates, Limitations

    Rutherford Atomic Model Experiment, Postulates, Limitations. Rutherford Atomic Model or planetary model of the atom relates the atomic structure of elements which was proposed by Ernest Rutherford in 1911. This model described that an atom in a molecule has a small, dense, and positively charged core called a nucleus.

  17. Rutherford's Atomic Model

    That's why his model is called the planetary model. Rutherford didn't know exactly where or how electrons orbit the nucleus. That research would be undertaken by later scientists, beginning with Niels Bohr in 1913. New and improved atomic models would also be developed. Nonetheless, Rutherford's model is still often used to represent the ...

    The experiments that were used to discover electrons and nuclei reveal some of the basic properties of atoms and can be readily understood using ideas such as electrostatic and magnetic force, already covered in previous chapters. ...

    The Nagaoka model is also known as the Saturnian atomic model or planetary model. This atomic model is a hypothetical model of the atomic structure, unlike Thomson's raisin pudding model. ... In March 1924, he described experiments where he claimed to have obtained one milligram of gold and some platinum. The discovery was made by subjecting ...
