WebOct 8, 2001 · This is expressed by Bohr’s quantum postulate: [… the] essence [of the formulation of the quantum theory] may be expressed in the so-called quantum postulate, which attributes to any atomic process an essential discontinuity or rather individuality, completely foreign to classical theories and symbolized by Planck’s quantum of action. WebBohr’s model had to be altered in order to allow for such decompo-sitions. He outlined this idea in a lecture in winter 1914/15, but did not publish it.

Energy Level - Bohr’s Atomic Model and Postulates of Bohr Theory

WebThe Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. Bohr 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. WebBohr’s model of an atom was the first model to incorporate the quantization of energy. It gave results similar to those obtained experimentally for hydrogen atoms. However, Bohr’s model had certain limitations. Limitations of the Bohr’s Atomic Model Bohr’s atomic model explains many features of the atomic theory, but it has its limitations. WebThe first postulate states that all matter is composed of atoms.
