WebThe important postulates of Bohr's model of the atom are the following: According to Niels Bohr, the nucleus of an atom contains neutrons and protons. Orbits are circular paths in which electrons revolve around the nucleus. The angular momentum of electrons is quantized in their orbits. Web21 Apr 2024 · Notice in equation 2.7.6 how the quantization of angular momentum results in the quantization of the radii of the orbits. The smallest radius, for the orbit with n = 1, is called the Bohr radius and is denoted by a0. a0 = 52.92pm = 0.5292Å.
