Rutherford atomic model

Rutherford atomic model, also known as atomic or atomic planetary model, was described by the atomic structure of New Zealand - born physicist Ernest Rutherford (1911). In this model, atoms are described as small, dense, positively charged cores called nuclei. Almost all the masses are concentrated in it. Like a planet turning around the sun

Like a series of experiments conducted by undergraduate Ernest Mazden in 1909 under the guidance of Rutherford and German physicist Hans Geiger, the nucleus was small to explain the scattering of alpha particles in thin gold leaf Please assume it is dense. As observed. This source can emit alpha particles (ie, positively charged particles 7000 times larger than the electrons with the same mass as the ruthenium nucleus) and is enclosed in a protective lead shield. After passing through the slit of the lead screen, the radiation is focused on a narrow beam. A thin piece of gilt was placed in front of the slit and fluorescence was generated as a counter for detecting alpha particles using a screen coated with zinc sulfide. When each alpha particle strikes the screen, a burst of light called flicker is generated. This can be seen with an observation microscope attached to the back of the screen. The screen itself is removable and Rutherford and his colleagues can judge whether the alpha foil is diverted by gilt

Most of the alpha particles are observed to pass directly through the gold foil, which means that the atoms consist of large open spaces. Some alpha particles are slightly deflected and show interaction with other positively charged particles in the atom. There are other alpha particles scattering at a large angle, but there are few even reflected back to the source. (Mr. Rutherford later told the famous saying "It got incredibly incredible hits like when throwing a 15-inch cannon on a thin paper and it hit you." As suggested by the nucleus, the target particle can explain this strong repulsion.The negative electron which is electrically balanced with the positive nuclear charge is thought to travel through a circular orbit around the nucleus The electrostatic attraction between the electron and the nucleus is compared to the attractive force between the rotating planet and the sun The majority of the atoms of this planet are open spaces and the resistance to the passage of alpha particles is There is none.

The Rutherford model is an alternative to the "May Pudding" atomic model of British physicist Sir J. J. Thomson. Electrons are embedded in positively charged atoms such as pudding plums. Based entirely on classical physics, the Rutherford model itself was replaced by the Bohr atomic model within a few years. And it combined several early quantum theories.

Rutherford's atomic model may be called Rutherford model or Rutherford model called nuclear atom. As you can see from the picture below, there is a big black ball at the center because the small red dot moving around the nucleus and its surroundings is electronic. Among the long lines of the Bohr family as a great physicist, the most typical member of the authors' opinion is Mr. Nielspor, Denmark. He received good advice from great past physicists J. J. Thomson and Ernest Rutherford. This also urged him to win the Nobel Prize in Physics in 1922. One of his best studies is his atomic model, commonly called the Bohr model.
