Bohr's theory; Bohr's atomic theory; Bohr model. A model of the atom that explains emission and absorption of radiation as transitions between stationary electronic states in which the electron orbits the nucleus at a definite distance. The Bohr model violates the Heisenberg uncertainty principle, since it postulates definite paths and momenta for electrons as they move around the nucleus. Modern theories usually use atomic orbitals to describe the behavior of electrons in atoms.
Model of the atom developed by Niels Bohr in which the electrons orbit the nucleus at specified distances.
Nils Bohr's model of the hydrogen atom, in which the energy levels are depicted as concentric circles of radii that increase as (level number)2.
A particular model of an atom, invented by Niels Bohr, in which the electrons are described as revolving about the nucleus in circular orbits.
Idea of the atom with electrons in fixed "orbits". Developed by Niels Bohr in early 20th century. Supports idea of ground state and excited state, and explains quantization of photons absorbed and emitted.
