WebPostulates of Bohr's atomic model: Bohr proposed that in an atom electron is revolving around the nucleus in a definite circular path called orbits or shells. These orbits are called ‘stationary orbits’ and each orbit or shell possesses fixed energy. The energy levels are represented by an integer called quantum numbers where n = 1, 2, 3,..... WebThe Bohr–Sommerfeld model (also known as the Sommerfeld model or Bohr–Sommerfeld theory) was an extension of the Bohr model to allow elliptical orbits of electrons around an atomic nucleus. Bohr–Sommerfeld theory is named after Danish physicist Niels Bohr and German physicist Arnold Sommerfeld.

WebLimitations of Bohr Atomic Model Theory. It violates the Heisenberg Uncertainty Principle. The Bohr atomic model theory considers electrons to have both a known radius and orbit i.e. known position and momentum at the same time, which is impossible according to Heisenberg. The Bohr atomic model theory made correct predictions for smaller sized ... WebBohr described the hydrogen atom in terms of an electron moving in a circular orbit about a nucleus. He postulated that the electron was restricted to certain orbits characterized by discrete energies. Transitions between these allowed orbits result in the absorption or emission of photons. http://philsci-archive.pitt.edu/4005/1/Bohr_April_2008.pdf solunar tide chart at imperial beach ca
