In the Bohr model of hydrogen atom, the ratio of the kinetic energy and total energy of electron in the n t h quantum state will be. Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii. The 1913 Bohr model of the hydrogen atom was replaced by Schrödingers wave mechanical model in 1926. The different atomic particles such as electrons, protons, and neutrons are shown at their predicted positions. This allowed for chemists to find a model of chemical bonding where the electrons in the outer orbits could be exchanged. This model is used to illustrate the atomic composition in pictorial form. The Bohr model of the atom is essentially that the nucleus is a ball and the electrons are balls orbiting the nucleus in a rigid orbit. How did scientists figure out the structure of atoms without looking at them Try out different models by shooting light at the atom. In this model n = ∞ corresponds to the level where the energy holding the electron and the nucleus together is zero. The ratio of kinetic energy and the total energy of the electron in the nth quantum state of Bohrs atomic model of hydrogen atom is. In 1913, a Danish physicist, Niels Bohr (18851962 Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. The Bohr model is also known as the Bohr-Rutherford model as it was developed as a modification of the Rutherford model. \) is the Rydberg constant in terms of energy, Z is the atom is the atomic number, and n is a positive integer corresponding to the number assigned to the orbit, with n = 1 corresponding to the orbit closest to the nucleus.
