The basic differences between Rutherford and Bohr's Atomic model are. Observation: Rutherfords model is based on gold foil experimentation and the Bohr model is related to the hydrogen line spectrum. The Rutherford model suggested the positive charge of the atom was concentrated inside the center of the atom. In constructing his model, Bohr was presented with several problems. The electrons can have only specific amounts of energy. Bohr used Planck's quantum concept to try to explain the Rutherford model of the atom. Because of such limitations in Rutherfords model, the Danish physicist Niels Bohr proposed a new model in 1913 based on the quantum theory of radiations. The orbits are labeled by an integer, the quantum number n. Electrons can jump from one orbit to another by emitting or absorbing energy. Key Differences Between Bohr and Rutherford's Atomic Theory Given points are the critical one to understand the difference between two theories: Rutherford's theory says that in the center of an atom is a small positively charged nucleus, which is surrounded by negatively charged electrons.

Bohr model is considered as a modification of Rutherford model. What is the difference between soy and estoy? Rutherford had discovered the nuclear atom, a small, positively-charged nucleus surrounded by empty space and then a layer of electrons to form the outside of the atom. In this model, Bohr mentioned that the most of the atomic mass lies in the central nucleus that contains protons and electrons are arranged in definite energy levels and revolve around the nucleus. Rutherford model was proposed byErnest Rutherford in 1911. It does not predict the relative intensities of spectral lines. To provide an explanation, the primary purpose of this experiment was to observe how alpha particles were reflected through gold foil. In the Rutherford model, the atom is made up of a central charge (this is the modern atomic nucleus (though Rutherford did not use the term "nucleus" in his paper) surrounded by a cloud of.
