In this model n = ∞ corresponds to the level where the energy holding the electron and the nucleus together is zero. The Bohr Model is known as a planetary model because these orbits. The Bohr Model has an atom consisting of a small, positively charged nucleus orbited by negatively charged electrons. In the Bohr model, the electrons travel in defined circular orbits around the small positively-charged nucleus. \) 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. The Bohr model of Carbon is drawn with only two electron shells, the first shell contains 2 electrons and the second shell contains 4 electrons. Bohr then used the mathematical relationships describing electrostatic attraction and centripetal force to show that his model of the atom was consistent with. The Bohr model was also the first atomic model to incorporate quantum theory, meaning that it’s the predecessor of today’s more accurate quantum-mechanical models.
