In 1909 the Geiger and Marsden experiment was . In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells.There are five basic atomic models which have contributed the structure of the atom itself. Rutherford had shown that the atom consisted of a positively charged nucleus, with negatively charged electrons in orbit around it.

Atomic Planetary Model: Basic diagram of the atomic planetary model; . artifactID: 1286741. So, we represent .Drawing the Bohr Model of Sulfur. Now that we know the two atomic models, let’s try to understand a few concepts. Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. As we know now, a positive charge on the nucleus is due to the protons.The goal of each atomic model was to accurately represent all of the experimental evidence about atoms in the simplest way possible.Schlagwörter:The Bohr ModelAtoms

By 1911 Rutherford had determined that the nucleus was about 10,000 times smaller than the atom as a whole.The planetary model may not be the ultimate, perfect model of the atom, but don’t underestimate its power. The current theoretical model of the atom involves a dense nucleus surrounded by a probabilistic cloud of electrons.Rutherford’s earlier model of the atom had also assumed that electrons moved in circular orbits around the nucleus and that the atom was held together by the electrostatic . While obsolete, Bohr’s Model of the atom was an important step. Thomson knew that atom had an overall neutral charge.
