WebBohr: In-depth work on Rutherford's model showed it had limitations. The electrons should just spiral in towards the positive nucleus. Electrons move in fixed orbits, ... WebThe plum pudding model did not last long however, in 1909 a former pupil of Thomson’s, Ernest Rutherford discovered that the atom itself had a mass of positive charge at the centre, contrary to the plum pudding model. It was through the Geiger Marsden experiment that Rutherford made this conclusion.

WebWith A. Sommerfeld’s extension of the Bohr theory in 1915–1916, it was turned into a powerful tool of atomic research and adopted and further developed by German physicists in particular. The new and more general Bohr–Sommerfeld theory described the atom in terms of two quantum numbers, while Bohr had originally used only one quantum number. Web4 de set. de 2009 · This model has some good ideas in it, but overall it has some problems. The key (and not incorrect points) of this model are: The atom is made of protons, neutrons and electrons. Most of the space ... Web8 de ago. de 2012 · We, as high school students have been taught that-because Bohr's model of an atom assigns specific orbits for electrons-that it is better than Rutherford's model. But what Rutherford failed to explain was why electrons don't emit EM waves & fall into the nucleus. I don't see how the introduction of 'atomic orbitals' overcame this defect. dynamic viscosity of ethylene glycol at 20 c
