Solar system model of the atom

4.2 Models of the atom | The atom

Another way of thinking about this model was that the atom was seen to be like a mini solar system where the electrons orbit the nucleus like planets orbiting around the sun. A simplified picture of this is shown alongside. This model is sometimes known as the planetary model of the atom. Figure 4.4: Rutherford''s model of the atom.

Bohr model

The Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1), where the negatively charged electron confined to an atomic shell encircles a small, positively charged atomic nucleus and where an electron jumps between orbits, is accompanied by an emitted or absorbed amount of electromagnetic energy (hν). [1] The orbits in which the electron may travel are shown as

When the analogy breaks down. Modelling the atom on the

Both the atom and solar system comprise of one central body/particle of a relatively large mass, ''encircled'' by a number of much smaller bodies/particles. The orbiting bodies are attracted to the central body by a physical force in both cases. If a pupil can visualise the solar system, then it may act as a model for these aspects of the atom. 4

In 1913, Bohr demonstrated that electrons moved around an atom''s nucleus in certain discrete energy "shells," and that radiation is emitted or

6.2 The Bohr Model

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model, since it pictured the atom as a miniature "solar system" with the electrons orbiting the

Atomic Models (IN ORDER) Flashcards

The discovery of the electron in 1897 led to this idea of an atom. This model is when something smaller exists inside an atom. Nuclear Model. Ernest Rutherford thought that most of an atom is empty space with a small, positively charged center. He discovered that an atom has a nucleus inside of it and called it the Nuclear Model.

Then books and written records became the main source of information that expressed the way the people of the time thought of the Solar System.

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

As re showed the atom with a nucleus and electrons orbiting around it, like the planets of the solar system, it became known as the planetary model. How did Bohr expand on Rutherford''s model of the atom? Niels Bohr related the line spectra of the elements. He used a hydrogen atom. So, in 1913, Bohr proposed some postulates that altered the

The Atom, Solar System, and Biology | Lungs

The perspective that the morphology of the atom is similar in many ways to the structure of the solar system was proposed by Niels Bohr in 1915 and has become known as the "planetary model" of the atom. The atom has a central body, the nucleus, around which the electrons orbit.

1 Atomic Theories Before 1913 | Niels Bohr and the Quantum Atom

The nuclear atom proposed by Ernest Rutherford in 1911 served as the foundation for Bohr''s atomic model, but at the time it was not widely accepted. The chapter further discusses the new ideas of atomic number and isotopy which were introduced shortly before Bohr came up with his quantum model of the atom.

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

Bohr Model of the Atom

Learn about the Bohr Model of the atom, which has an atom with a positively-charged nucleus orbited by negatively-charged electrons. The gravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively charged nucleus and the negatively charged electrons. Main Points of the Bohr Model .

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.

The History of the Atom – Theories and Models

Rutherford''s discovery of the nucleus meant the atomic model needed a rethink. He proposed a model where the electrons orbit the positively charged nucleus. While this was an improvement on Thomson''s model, it didn''t explain what kept the electrons orbiting instead of simply spiralling into the nucleus. Enter Niels Bohr.

Rutherford model

OverviewBackgroundExperimental basis for the modelContribution to modern scienceExternal links

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 for the atom, based on the experimental results, contained new features of a relatively high central charg
