Uncertain explanations about the spectrum and stability lines of an atom are available. Your email address will not be published. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump. Complete Step by step solution: - Bohr's model of the atom was based on quantum theory where the electrons move around the nucleus in definite orbits. The Rutherford model suggested the positive charge of the atom was concentrated inside the center of the atom. He performed a famous experiment whereby atomic particles were passed through gold foil to measure their mass and size. The Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. Later on, a physicist put forth another principle called Heisenbergs uncertainty principle, which explains the impossibility of the simultaneous determination of exact position and momentum of small moving particles such as electrons. 4/5 Orbits around a nucleus of an atom based on Bohr's atomic model (Reference: aplustopper.com) Orbits are predictable paths taken by electrons.
